Branding, themes, and names

A good marketable product needs a brand name. With its own name, customers can more easily refer to your product and you create a more memorable experience. After a good reputation has been established your brand name can help sell other products since people know they can expect quality products from a reputable brand. Lastly, branding helps to set your product apart from competitors [1]. There are entire studies and companies that solely focus on branding and marketing. Branding is not really an area on which we have decided to spend our limited resources for this assignment. However, we did brainstorm on some names and themes for our smart plant pot. We have concluded that theming the pot was unnecessary for this prototype. We considered giving it a pop-icon theme that would be recognised and like by most users, but this very quickly leads to problems with copyright. Secondly, we feared that theming the pot would take away attention from the display and lights that the pot uses to gain the attention of the users in its surroundings. Thirdly, we thought that the caretakers might prefer a clean white design as opposed to a spiderman-pot with a tulip in it. The caretakers are the ones who have to purchase and install the system, so their preferences are also of interest.

For the name of the product, we have considered a few options. In the end, we have decided to go with FLEUR. This is a common Dutch name that is easy to remember and pronounce. FLEUR is a name derived from words for flower or flowering, we found this to be fitting since our product is designed to house a plant, of which many have flowers and in our test period we will fill it with a tulip.

Idea

The idea is to create a smart plant system that would notify the user if it needs either water or more or less sunlight. The target group is a social work space (zorginstelling) for mentally disabled people. They can see or hear which plant needs attention and get that plant what it needs. The social workers will therefore do something useful which is very great for such people. The people monitoring this social work space will also get a great work relief because of this system because they don’t have to tell these people what to do with the plants anymore. The plant pot will probably get a nice face so that it looks like a friendly robot and it will get water sensors implemented in the soil and light sensors around the plant to monitor the amount of light the plant gets. The pot will also be able to notify when it is being moved or given water and will start saying nice things to the person moving it or giving it water.

USErs

User

The main target group for this product is people with a mental disability. The product is designed to help the users overcome some of the challenges that they face due to their disability. "Mental disability" is a very broad term and can out itself on a whole spectrum of problems, ranging from difficulty with speaking to recognising emotions. For the sake of making a more tailored product, we have decided to focus on people with Down syndrome. This decision allows us to gather more specific needs and requirements from the users (which can be found in its own section).

Our robot will notify the user by speech when a plant needs more or less water, or more or less sunlight. This way the product helps the user take care of a plant without having to do complex tasks like remembering when and how often a plant needs water or sunlight. Our robot gives simple, chopped up clear instructions so that the user knows what is being expected from him/her. After a task is completed, the robots will give confirmation in the form of positive feedback to the user. This helps assure the user that a task has been successfully completed. This way our product makes caring for plants more accessible for people with Down syndrome. which has all types of benefits (see Sources XXXX)

The secondary users are the caretakers. The product is meant to be used by people with Down syndrome but is meant to be bought and installed by the caretakers. This device helps relieve workload from the caretakers by automating a part of the managing and task distribution process in a social work environment. Therefore it is important to always be mindful of who the users of specific functions is and what their needs and capabilities are.

Society

Some say that a society is measured by how it treats its weakest members (famous misquote NOT by Ghandi {Does this need an extra source?}). We realise that our product will not solve any world crisis or drastically improve the farming capacity of social workspaces, but it helps people who need a little bit more care. Our robot allows people with Down syndrome to more easily perform work, giving them a way to spend their day and make themselves (somewhat) useful. This benefits society by allowing better participation across all layers of society and show empathy and care toward those who need it the most.

Secondly, this helps relieve some of the workload of social caregivers who are often overworked. Financing for this sector generally low {does this need a source?} and our product might save some valuable time by automating some simple repetitive tasks.

Enterprise

This product of course has to be developed and manufactured. This creates jobs and potential revenue which is all good for the economy. Products of these types do already exist (see sources XXXX) but there are mainly focused on increasing greenhouse yield. This product has a different goal and is therefore unique enough to not have to deal with fierce competition in the market, giving it a fair shot at succeeding in our opinion.

Approach

In order to achieve the goals and milestones, a good approach need to be made and followed. x% of the people born everyday, is born with a mental disability like Down Syndrome [source]. A lot of those people live in care homes where they are loved and taken care off by the caretakers. Though the mental disabled live in a care home because they cannot live independently, it brings great satisfaction to be as independent as possible [source], and thus we designed a tool that helps them with that.

Our system will be placed in a plant pot, in the ground of the plant and on top. It will detect whether the plant needs water or whether it needs to be placed in the sun or if it needs shade. When it detects it needs those changes, in other words when the plant needs to be taken care of, the system will ask for this.

To achieve our goals, we first need to read ourselves into the subject. Literature study is needed to understand the problem we want to make a solution for; for whom exactly we are making the system and what it needs to be capable of. Therefore a USEr analysis needs to be made. This reflects on our solution to the problem from the perspective of the user (U), how it will benefit the society (S), and how it will be realistic from and beneficial for the enterprise (E). Also an RPC (requirements, preferences, constraints) list for the system and a list of user requirements need to be made.

Parallel to that, we need to think about the technical side of our system. Research about the components needs to be done, as well as a circuit model, the software of the system and the 3D-printed plant pot. When the components are arrived, the system will be built and the software will be uploaded to make sure the system works like we imagined beforehand.

Because of the fact we are designing a solution to a problem that involved mental disables people and their caretakers, the best research, next to literature study, would be to hear it exact form the people involved. Via contacts, an appointment for an interview will be made with a caretaker for more understanding of the problem and to get feedback on more useful functions of our plant pot system, as well as to remove unnecessary parts. Also we need to test our system in the real world. Therefore, in the meantime the experiment must be prepared and executed on time.

Goals

To make a successful project that can be shown to be successful, we need to define clear measurable goals and a way to test them.

Our main goal is to add something to the daily lives of people with DS. We want to give them a way to spend their time, and give them something to care for. Interacting and caring for the plant should be a hobby, something that they enjoy doing and spending time on. This is a beautiful idealistic goal that improves the wellbeing of these people and can therefore be marketed as a healthcare product that could even be covered by healthcare insurance.

This can be measured by keeping track of how much time is spent interacting with our pot compared to a control plant that does not have our systems attached to it. Secondly, we can question the users about their overall experience with our product. We do this by asking the users to rate individual aspects of this product on a 5 point scale as an improvement over normal plants? This way we get a quantitative measure of what our system adds to the weekly routine (time and enjoyment wise).

Our second goal is to improve the independence of the users with DS and teach them how to care for something. Our product provides routine and clear simple instruction. This will help the people with DS to take care of the plants themselves without any external help from caretakers. This improves their independence which is a trait that is heavily valued by the caretakers we interviewed. When these people become more independent they require less care and gain more freedom, which improves their quality of life. Secondly, this product will develop the skill to care for something. This is a useful skill for people who need care. If you teach these people basic caring skills they can help themselves and each other better.

Testing the increase in independence and caring skills from 1 week of usages will be difficult since changes are expected to be small and these characteristics are not so simple to measure. Hence this will probably be assessed by the caretakers who will be present during the testing stage.

Our third goal is to remove some workload from the caretakers. We know that it is not always easy to work in the (health)care sector and especially with the covid-19 situation the pressure on these people is high. If our product manages to independently keep the people with DS occupied, it will mean more free time for the caretakers to spend on others work or just relax a bit so this goal ties in with the second goal.

This can be tested by comparing the time a caretaker spends on helping these people take care of normal plants VS the time spent installing and explaining our product. If our product proves to be too complicated to use, we can get feedback from the caretakers that it took too much time and energy to adapt to the new system and that it was not as independent as we had hoped.

Our fourth and least important goal is to improve the health of the plants. Having healthy plants benefit the air quality and the overall look of a space [SOURCES]. Secondly it is nice if the care institution has to less regularly buy new plants, this saves time and money (which are already scarce resources).

This can be tested by starting off with two plants of the same type and health. One will be the control plant and the other will be planted in our pot. Both will be placed in the care home. After the testing period, the health of both plants will be assed. We do realise that assessing plant health is a bit subjective and that the sample size is really low, but we have to make do with what we can do in the restricted time and budget. It is also interesting to note that a smart pot that improves plant health is also an interesting product for the agricultural sector and greenhouse industry, seeing how dutch farmers need to produce with high efficiency to compete in the market because of the high prices for ground.

Experiment

To test whether our smart pot achieves the stated goal we will perform two simultaneous tests that are one week long. For each test, we will need two similar plants that are in similar health. The plant that we have chosen for this experiment is a tulip with a bulb. This was done because 1) they are available in this spring period. 2) They are flowers so we expect them to show relatively large changes over the short testing period of one week. 3) Because they are flowers we hope that the caretakers and the clients like them. 4) The blub prolongs the life of the tulips compared to cut flowers. This way we want to prevent the tulips from dying naturally within a week. 5) Because of the bulb we can plant the tulips into the dirt. Otherwise, it would have been a smart vase, which makes the needs for a moisture sensor obsolete. 6) bulb-in-pots need a bit of water once or twice a week. So the clients actually need to water the plants within that week. 7) Tulips require sunlight but not full sun. This is a bit more interesting in terms of programming our software and using the sensors.

In the experiment, one plant will be placed in a regular pot and will serve as a control. The other plant will be placed in our smart pot. Both plants will then be placed in similar environments (with the same temperature and amount of light) but in different locations (as to not trigger care for the control plant by association with the smart plant). Then the caretakers will introduce the people with DS to the plants and the smart pot and tell them that they have to care for these plants during that week. The caretakers also mention that one plant is a magical talking plant and that it can communicate if it needs something so that the clients will not be scared or too confused.

We know that one week is a very short time span and that a sample size of N=2 is small but we have to work with what we have. After the test period, we will assess the health of both plants to see if one is in better health than the other, suggesting the smart plant influenced the wellbeing of the plant. Due to the situation with Covid-19 we are not allowed to enter the care-houses in person. And due to the mental vulnerability of the clients, their privacy, and the fact that we are strangers to them, we are not allowed to set up a webcam feed to more scientifically measure some parameters like: time spent with the plant. Therefore we will gather results by questioning the caretakers (and the clients indirectly). The results from the two parallel tests will be combined, paying attention to any possibly interesting similarities and differences. From these combined results we will be able to judge whether our product achieved the goals we set for it, and what still needs improvement.

Hypothesis

We expected that we will achieve our main goal of helping people with Down syndrome to have more ways to spend their time in a joyful manner, that is why we decided on this design. We are fairly confident we will reach this prioritized goal when the design experiences no malfunctions during the testing period. This concretely means that the caretakers will rate the “time spend” and “enjoyment” in the questionnaire higher for our smart pot than for the control plant. Our second goal is to take some workload from the caretakers. For this, we expected a negative result but that is due to an unresolvable flaw in the design of the experiment. We hypothesize that the installation process adds extra workload, and so does the becoming accustomed to using the product. We expect that the clients will need some time and guidance from the caretakers when using the smart pot for the first few times. However, we do expect the workload to drop after the product has been fully integrated. Therefore we will also ask the caretakers if they foresee a reduction in workload if the smart pot were to be used longer than a week, say a month. For this, we do expect a positive answer, at least for the client who possess the necessary intellectual capabilities to learn and remember some new skills. Our third goal is to help the client to become more independent and caring. We expect that these characteristics will be hard to measure with such a small sample size and test time. But we might be wrong. It could also be the same that some clients quickly develop a caring fondness for the talking tulip (POSSIBLE NAME?). This again will have to be rated by the caretakers. We expected to measure some degree of increased independence. An increase in independence is defined as a report by the caretaker that the clients get activated by our system to perform a task that they had forgotten in the control plant. Our final goal was to improve the health of the tulip. For this, we expect an inconclusive result. We think that there will be no significant change between the control plant and the smart pot in one week, even if the control plant gets completely forgotten. On the other hand, it could also be the case that our plant model is not ideal or if the instructions aren't followed carefully enough by the client. Which may lead to drowning the smart pot tulip whilst the control plant lives.

Email with questionnaire for hypothetical use

Beste meneer/mevrouw,

Wij zijn een project groep aan de technische universiteit Eindhoven die bezig is met het ontwikkelen van een slimme plantenpot voor mensen met een verstandelijke beperking. Ons systeem moet het verzorgen van een plantje eenvoudiger en leuker maken om zo de dagbesteding en zelfstandigheid van deze mensen positief te beïnvloeden. Om tot het beste ontwerp te komen zijn wij meningen aan het verzamelen van mensen met ervaring in het vakgebied. Wij zouden enorm geholpen zijn als u kort uw mening zou willen geven over ons concept. In de bijlage vind u een korte beschrijving van ons systeem en 4 stellingen waar u een mening dient te omcirkelen, dit alles zal maar 5 tot 10 minuten duren. De antwoorden zullen alleen gebruikt worden ter sturing van het ontwerp proces en we zijn niet geïnteresseerd in persoonlijke gegevens van wat voor vorm dan ook. Als u vragen heeft of meer wilt weten over ons concept beantwoord ik ze graag.

Alvast bedankt en met vriendelijk groet,

Namens de gehele project groep,

Marijn Borghouts

Bijlage

Deze bijlage bevat een korte uitleg over ons concept, opgevolgd door een vragenlijst met slechts 4 stellingen en wat ruimte voor algemene opmerkingen.

Ons concept Planten in huis zorgen voor een leuk aanzicht en voor frisse lucht. Daarnaast kan het verzorgen van planten voor mensen met een verstandelijke beperking goed zijn voor het ontwikkelen van een zorgzaam karakter en het leren volgen van tijdsgebonden routine. Aangezien een plant in een potje met enige regelmaat water nodig heeft. Ons ontwerp beoogt deze positieve effecten van het verzorgen van planten te behouden terwijl het eventuele drempels uit de weg neemt. Daarom hebben wij een slimme plantenpot ontworpen. Deze pot houdt met sensoren de vochtigheid van de grond bij en de hoeveelheid zonlicht die er op de pot schijnt. Aan de hand van deze gegevens bepaalt de pot zelf wanneer het tijd is om de plant die er in zit water te geven of wanneer deze in of uit de zon moet.

De pot doet dit door op een vriendelijke en positieve manier te communiceren met zijn omgeving. De pot beschikt over een speaker, led-lampjes, en een schermpje om zo op verschillende manier de aandacht van iemand in zijn omgeving te trekken. De pot zal dus bijvoorbeeld hardop zeggen dat hij dorst heeft en graag een beetje water wil. Daarbij knipperen er dan blauwe lampjes en is het symbool van een gieter te zien op de pot. Doordat de pot duidelijke korte commando’s geeft en daarna de gebruiker bedankt bij een volbrachte taak hopen wij betrokkenheid en plezier bij de verzorging te vergroten, en de persoon in kwestie zelfstandiger te maken. Aangezien de slimme pot zelf de gebruiker aanstuurt zou dit een klein deel van de werkdruk op de verzorgers kunnen wegnemen.

Vragenlijst

Bij elke stelling dient u één antwoord wat van toepassing is te omcirkelen. Daarnaast is er open ruimte om uw menig te geven of uw antwoordt toe te lichten. Alle feedback is welkom, ook kritische uiteraard. We hebben liever te veel dan te weinig informatie dus wees niet terughoudend.

Results

This questionnaire was send out as an email on Thursday the 13th of May to 13 new, not yet approached, care institutions that were located in Brabant or Limburg.

Questionnaire after prototype use

The caretakers that we are in contact with prefer a questionnaire in Dutch so that is why this section is written in Dutch. It is important to keep the questionnaire short with only the most vital questions. The caretaker are voluntary helping us by spending their time on using our product and answer our questions. Be do not want to burden them or scare them off. Secondly, we think that it would be better to have few complete and carefully answered vital questions instead of 30 questions that are answered minimally.

Beste …, Nogmaals bedankt voor uw medewerking. Afgelopen week hebben u en uw cliënten onze slimme pot getest. Hieronder bevindt zich een korte vragenlijst met 8 stellingen over jullie ervaring met de slimme pot. Het invullen zal ongeveer XX minuten duren. Wij zullen deze resultaten alleen gebruiken om te beoordelen of ons prototype heeft voldaan aan vooraf vastgestelde doelen, en wat er bij een volgende uitvoering eventueel verbetert kan worden. Enkel wij als project groepje en onze supervisors zullen de antwoorden lezen en we zijn niet geïnteresseerd in privé gegevens zoals namen. Bij elke stelling dient u één antwoord wat van toepassing is te omcirkelen. Daarnaast is er open ruimte om uw menig te geven of uw antwoordt toe te lichten. Alle feedback is welkom, ook kritische uiteraard. We hebben liever te veel dan te weinig informatie dus wees niet terughoudend.

• The second deliverable will be our physical prototype of the greenhouse climate management system.

• The third deliverable is the final presentation, in which we present our project for our teachers and peers.

Milestones

• 1: Literature study
• 2: Make an RPC list
• 3: Make a BOM list
• 4: Ordering of the parts
• 5: Software development
• 6: Making the prototype
• 7: Make the final design
• 8: Finalise the wiki page

Objectives

Cost efficient/Affordable

The prototype should make optimal use of the available resources. Furthermore the components and assembly process should be as cheap as possible to reduce the total production cost, making the design cheaper for users (or obtaining a bigger profit margin for the vendor)

Easy to use

The prototype should be easy to install and operate. This is especially important considering the target audience of mentally handicap people. This product is designed to help these people with doing more complex tasks. If the operation of the product is not extreme straight forward it will only work counter effectively.

Friendly/Positive reinforcement

We want the product to interact nicely with the user. The product should communicate with the user in a friendly manner and compliment the users when they perform an action. This makes the product more pleasant to use and the explicit positive reinforcement confirm to the mentally disabled people that they are in fact doing a good job.

User Needs and Preferences

People with Down syndrome have different needs and preferences compared to people without intellectual disabilities. A good product should address all of the users needs and as many possible preferences. So in order to develop a good product one should have a clear idea of what these needs and preferences are. To gather this information we have called several care-institutions asking them if they would be interested in helping us answer some questions and/or help test the first prototype. Secondly, we decided to also do a literary study into this subject to obtain even more information from other sources.

From the literature we have found that language development is moderately to severely compromised in some children with DS and that therefore most individuals with DS also have less developed language skills at all ages in life compared to people without an intellectual disability (Lemons, 2010) and (Chapman, 2000) To accommodate for this lack in linguistic skills there are a few things that one can do to improve communication with people with DS.

Of course there are more items, but these were the ones that we identified to be the most important and the ones that we could play into.

Questionaire answers from a caretaker

In order to get a deeper understanding how people with Down's syndrome would or could react to our project contact was sought with a caretaker. This caretaker has around 10 years of experience with these particular patients, this means that the answers to the questions are usefull to the project at hand. In the following text first the questions will be posed after which the answers are written. Lastly some extra pointers given by the caretaker will be mentioned.

Q) What would people with Down's syndrome need in daily life that this plant can help with?(To combat boredom for example)

A) Becoming more independant, that is a hot item at the moment. Caretakers want theur patients to be able to live as long as possible on their own.

Q) Do you think that our project can improve their daily life?

A) Not only do plants make sure that there is cleaner/better quality of air in the patients room, but they also get thought to take care of the plant in a creative and playfull manner.

Q) Do you think that our project would need to het more funtions?

A) Only sound might not be enough, it can become quite noise in care homes. But these patients also react very well to a combination of visual and auditive stimulation. The visual stimulation does not need to be complicated, colors would suffice, so for example a yellow light means more sunlight or a blue light means more water. This way they also get a more satisfactory feeling in the long run. These patients also forget general tasks quite a bit, this would be giving water in regular intervals for example, a solution would be the use of so called 'pictokaarten' and a weekly schedule. These pictokaarten are designed to not give any confusion on the action that has to be taken and the weekly schedule gives them a place where they can easily find the tasks that have to be done on a certain day. Direct tasks, for example more sunlight, would be perfect in an visual/auditive stimulation.

Q) What would be the best way for our project to approach people with Down's syndrome?

A) The best way to approach them is in a positive and cheerfull way yet the message has to be simple and clear, and thank/compliment them if they performed the task well. For our project the following 3 suggestions were given: 1. 'I am thirsty, could you give me some water?', 'Thank you, now I am not thirsty anymore.' 2. 'I am quite hot, would you mind placing me in the shade?', 'Now I am nice and cool, thank you.' 3. 'I am quite cold, would you mind placing me in the sun?', 'Thank you, now I am not cold anymore.' What might help the patients in the long run is some sort of checklist, these already get used now to see if they keep getting a better understanding of the tasks they are performing. This checklist could ask what color lamp has what meaning for example, this can then be excecuted with their caretaker.

Some general remarks.

• People with Down's syndrome have different levels of mental capabilities depending on their IQ. The caretaker mentioned that our project would work best with patients that have the same mental capabilities as 6-10 year olds. Some level of understanding is needed since we are trying to learn them to care.
• They love cables that they can see. These have to be tucked away, it might not harm them but they will pull on them.
• the site botsbegleiding.nl(teachh) can be used as a usefull source, it officially is a site for autism but the thought processes are quite the same as those we can use.

Promo Video

This video needs to be very short <100 seconds. Otherwise, people lose their attention. The goal is to clearly show what our product is, what it does, and how it looks.

As an example, you could look to nearly every IndieGoGo/Kickstarter video. I have found a video of the LUA pot. This is extremely similar to what we have and could be a great inspiration. https://mu-design.lu/lua#super-simple-app The hook Your Kickstarter videos have to get their attention. If you don’t do this, nothing else matters. This could be through the video title or those first few impactful seconds that draw the person in to learn more.

Tell a memorable story

Your video should tell a story. If you are trying to get funding for something that solves a problem. The problem should be demonstrated through a visual narrative. Stories hold attention. They show rather than tell. People want to find out what will happen next. Work the narrative to hold attention to the very end. And after the viewer walks away, they should be left with an imprint, an inability to forget what they just saw, and hopefully and urge to share.

Get people excited

Yes, you are very excited about the movie for which you need funding, but is this excitement translating to someone who knows nothing about you. What is unique and special about your idea? Why should the contributor want to be a part of your mission? And don’t underestimate the power of music to inspire excitement.

Make sure visuals match the script

If you reference a mouldy cheeseburger in the script for some strange reason, we need to see one. The visuals need to synch to what the actors are saying to reinforce your message.

Don’t over-explain it

You don’t want to be too vague. People should know what they are funding and need to know that you have a plan. But a lengthy video that explains every detail of the process will not serve you well. The most successful videos are concise 2-3 minutes.

Discussion

During such a project there are always things that could have gone better. Some of these things were anticipated and others were not. This section is dedicated to the things that went suboptimal, and how we would improve a second prototype.

The first big problem that we encountered had to do with our target audience, namely people with down syndrome. In order to obtain user “preferences and needs” we needed information from these people. Although Down syndrome is not a rare disability (1 in 800 births in the united states SOURCE), we personally do not have contact with anyone suffering from this condition. This is because these people generally have fewer social contacts. So we tried getting in contact with care institutions. This was quite hard since these caretakers told us that they have busy jobs and people generally dislike spending time helping complete strangers when they are busy. Another factor that did not help is that the caretakers are very protective of their clients. Since the clients themselves are not able to properly fend for themselves. Lastly, the coronavirus made it impossible for us to visit these places in real life. So in another project, we could think of better ways to get into contact with our target group (or decide upon an easier one during the first stages of development).

Another problem we encountered had to do with our goals and experiment. As a goal, we aimed to add a new joyful activity to the day of people with Down syndrome. The main problem here is the measurability of these results. Due to the coronavirus, we could not be present in persons to judge the effectiveness. And due to the privacy of the users, we also could not install camera’s for example to keep track of how the prototype performs. The result of this is that we had to ask the caretakers to pay attention and all the feedback had to come from questioning those caretakers. This is less than desirable because we want to ask as little as possible from these people since they are already being extremely friendly and helpful by testing our product. Secondly, it increases subjectivity in the results since both prototypes are judged by different observers. This could be solved by perhaps waiting until covid passes or by finding a different target audience that allows us to monitor the experiment ourselves.

An additional problem of the experiment was the test period length. Due to the structure of this course, we could only permit 1 week of testing. This is really short when you want to monitor potential changes in behaviour and the health of plants. Expected changes are minimal in one week, and therefore the results might be inconclusive. We have no good fix for this.

The next thing that we would improve in a new version would be the design of the pot and how the sensors are placed inside. In the current design, the moisture sensor fits into a hole that is halfway down the pot. This was the only way everything would fit in the pot. Making the pot bigger was not an option since we were restricted by the size of the 3d printer and the print time. This low hole caused excess drained water to drip through the hole in the direction of the electronic core. This is obviously a problem. In the prototype, this was fixed by using some tape. But a more ideal permanent solution would be to redesign the pot with a bigger 3d printer. Or by using moisture sensors that are smaller since our model was quick large (8ish cm in length.)

FLEUR now uses a powerbank as the source of power. We didn’t like to option of having a power cable since that would look less nice and would increase the risk of electrocution because we use electronics inside a flowerpot that is filled with water every week (and see the problem of the hole described above). The downside of using a battery is that you have to swap or charges them once in a while. So to minimize that labour and make our system more durable we should use power-efficient component. In the current design the display of the mstack 5 core uses most of the power (XX Watts), our sensors take a measurement once every XX minutes Template:And after the button is pressed, to ensure fast feedback. This power consumption is negligible in comparison. So to improve our design and make it run on smaller and fewer batteries we could swap the standard transmissive display for a so-called reflective display, these are the ones that are used in e-readers. These displays only use energy when the projected image on the screen has to be changed. Which is only a handful of times a day in our case. This would increase our average power consumption from XX watts to XX watts, allowing for smaller batteries.
