Introduction
Problem Statement:
Many homeowners have aquatic pets of certain kinds either for aesthetic reasons or out of genuine compassion for the animals. In the world of aquariums and fish, one of the most important things is ensuring healthy water conditions. There can be various reasons for people to wanting to own an aquatic pet. It can be difficult to ensure these parameters with insufficient knowledge or time constraints. An aquarium owner comes across various tasks and problems. Owning and maintaining a fish tank can be difficult. These include feeding schedules, water parameters, pH-levels and temperature. It can be difficult to test regularly and keep values on certain levels. All these factors can have negative impact on the fish their health and happiness. For many aquatic pet owners, it can be helpful to have a tool that takes care of the fish during periods of absence. This will prevent stress and illness among the animals in the tank.
Our proposed solution is an aquarium robot, that will be able to monitor and maintain water parameters. Our system aims to take away most difficulties that arise when owning an aquarium. This enables the user to ensure optimal chemical levels and temperature. Our system will be able to sense the tank its temperature, pH, turbidity and ammonia levels. The sensors are selected such that they will withstand the constant exposure to water and give accurate results. A microcontroller acts when certain levels get out of balance. Dispensing the correct amount of food on certain times during the day can be important too. The system will be able to dispense food when needed. By using Wi-Fi and an application, the system will be able to contact the user and send real-time values to the user. This and other actuators will ensure safe, preset values inside the aquarium. The user will get notified when a problem arises, and inform the user about its actions.
Objectives:
The objectives of our device are that:
- It should be slash resistant, only the sensors will get submerged.
- It should be safe for the fishes
- It should continuously collect sensor data (PH, temperature and ammonia concentration)
- It should be able to act when an issue arises
- It should inform the user via an app if there is an issue detected and state its action (high or low PH level, unstable water temperature, unsuitable ammonia concentration)
- The user should be able to set the optimal environment parameters for the aquarium (with initial recommendations for new users, maybe per species of fish)
- App should inform the user of potential solutions for the issue (if there are major issues/ problems)
- Inform the user once a time that everything is fine.
- Inform the user supplies are low (in case of pH control system, chemicals)
Users:
- Homeowners with Aquatic Pets: These users keep fish or any other aquatic creature simply for the sake of aesthetic enjoyment or as a hobby. They may have various levels of expertise when it comes to maintaining an aquarium's optimal condition, from beginners, who might lack detailed knowledge about the different needs of their aquatic pets, to enthusiasts with plenty of experience.
- Veterinary Clinics: Professionals who provide medical care or rehabilitation for aquatic animals could use the system to monitor and ensure the health of their aquatic patients.
- Educational institutions: Institutions such as schools and universities that use aquariums for educational purposes may benefit from the device to teach students about marine life care
- Maintenance Services: Experts who have to maintain aquariums for clients could use the device to provide excellent quality services while ensuring long-term health and stability to the aquariums.
What Do The Users Require:
- Ability to remotely track and monitor environmental changes such as pH, water temperature and ammonia concentration in the fish tank through an application on their phone or websites.
- Ability for them to set their own ideal parameters in the application (with suggestions of what these ideal parameters could be for certain scenarios).

Design
The choice has been made to make a all-in-one connected fish tank automation system. The system would keep track of the water temperature, pH, turbidity and ammonia levels. Temperature would be adjusted automatically with the activation of a heater if it falls below a threshold. Furthermore the system would dispense a certain amount of fish food at a certain frequency given by the user. The system would be a box to be attached at the top of a wall of the tank, just above the water. Temperature, pH, turbidity and ammonia sensors, as well as the heater would at the bottom of the system, submerged in the water. Inside of the box would be a microcontroller, a wi-fi module, and the food dispensing system, composed of an Archimedes screw controlled by a servo motor and a food tank.
This system would be coupled with a mobile app, on which the user would be able to see the parameters in real time and be notified if one of them is out of its normal range, with advice to fix them. The user would also be able to input parameters to decide on the quantity and frequency of food dispensed.
Research on aquarium environment parameters and optimal conditions for ornamental fish
As the selected user group for this project is home owners with ornamental fish aquariums and aquarium stores that may also breed their indoor ornamental fish, the optimal conditions coincide for these user groups as they all involve small scale indoor freshwater aquariums as the environment. The water condition factors that affect general living and breeding conditions of ornamental fish are temperature, hardness/softness, pH, ammonia concentration, chlorine concentration, carbon dioxide and oxygen.
Temperature of the water
The temperature of a fish tank is usually a main concern during the transport and introduction of new fish due to risks of thermal shocks the fish can get that can be caused when a rapid change to the temperature in their environment occurs (2). For general health and well being of fish, temperature requirements are split into two types: cold water fish and tropical fish. Common cold water fish include gold fish, Koi and certain species of barbs, tetras and loaches. Common tropical fish include bettas, Guppies, Mollys and certain species of laches and tetras. These two types different types of fish should generally not be in the same aquarium due to the different temperature needs. While tropical fish can tolerate 21 °C up to 30 °C, the optimal conditions for tropical fish are 24°C to 27°C with 27°C to 28 °C being suitable for breeding of many types of tropical fish (3). Temperatures above 32°C, are detrimental to the health of most fish. As for cold water fish, they can tolerate from 15°C up to 24°C. With some specifies preferring temperatures lower than 15°C (4).
In cases of the fish tank temperature getting too low for the fish types, solutions include simply increasing the temperature of the room or installing water heaters that are generally heating coils enclosed in a glass tube. A water heater of 5 to 6 watts is required per gallon of water (2).
In cases of the fish tank’s temperature being too high, solutions include reducing artificial lighting over the tank or blocking out natural lighting, cooling down the room that the tank is present in, installing better filtration systems to cycle water faster and even simply running a fan on the water’s surface (5).
Hardness of the water
General hardness or total hardness refers to the measure of calcium and magnesium salts as well as other ions such as sulphites and chlorides of magnesium and calcium present in the water. Below 75 ppm water is considered as soft. From 75 to 150 ppm is moderately hard and 150 to 300 ppm is hard. Beyond that water is considered very hard. Most freshwater fish can thrive in a wide range of hardness and most of the time does not require any water treatment unless fish known to come from regions of extreme total hardness (either soft or very hard) is being raised (6). Water hardness anywhere from 100 to 300 ppm is known to be optimal for growth of most ornamental fish. Only when general hardness is below 12 ppm would require liming (3).
pH
pH refers to a logarithmic scale of hydrogen ion (H+) concentration in aqueous solutions. For most ornamental fish, a pH of 7 to 8 is suitable for growth, breeding and general health (1). But the pH levels must never fall below 5 and raise above 8.5 for aquarium water. Certain ornamental fish prefer slightly acidic water (with pH of 6.2 to 7) such as rosy barb, tiger barb, tetra, angel and daino. Fishes like koi, goldfish and cichlids prefer slightly alkaline water (3). pH can be increased if necessary with doses of calcium hydroxide and decreased if necessary with acids like hydrochloric acid.
Ammonia concentration
Fish waste contains many end products of nitrogen metabolism such as uric acid, urea ammonia. With ammonia being one of the most hazardous to fish. In water, ammonia exists as either NH3 in its gaseous state or in an ionized state as NH4+. It is the unionized state (NH3) that is harmful to fish as it damages gills and causes fish to gape for air at the water surface (although other issues could also lead to similar symptoms). According to Subhendu Datta’s paper on aquarium water quality management, 0.4 ppm of NH3 is considered acute toxicity level meaning a short term or single dose can be lethal. While 0.05 ppm of NH3 with long term exposure can lead to the above mentioned symptoms. Damage to gills can already occur at 0.25 mg/lt (2). Ammonia poisoning is mainly a concern when the fish tank is first established and still lacks a strong cultivation of bacteria that break down these harmful compounds. These bacteria mainly reside in the filters of the water cycling and filtering system and hence require ample time with batches of feeder fish before the ornamental fish can be introduced to an aquarium. The ideal ammonia concentration in the system should be trace amounts (it should be noted that ammonia testing kits usually measure both NH3 and NH4 combined). In events of sudden ammonia spikes, fish should be transferred to other tanks (being mindful of the necessary procedures to avoid thermal shocks) and allow the bacteria load to increase and break down the ammonia. Other discouraged solutions include using ammonia detoxifiers (2).
Other than when the aquarium is first established, ammonia concentrations can also increase when too many fish are added at once, the fish tank is heavily populated, the filtration system is not functioning properly or is insufficient and when the fish are being overfed. Apart from factors that increase ammonia concentration, the toxicity of ammonia can also increase at higher water temperatures and pH levels above 7.0 (6). This is because the equilibrium between NH3 and NH4+ is dependant of pH and temperature and yield of NH3 is preferred at higher temperatures and pH which should be taken into account as NH3 is 300 to 400 times more toxic to fish than NH4+ (1).
Chlorine concentration
Tap water is a readily available source of clean water that can be used to fill fish tanks. However, the main issue with this is chlorine content in tap water. Chlorine amounts as low as 0.1 ppm is enough to be considered toxic for most ornamental fish (3). However, this can easily be solved by letting the water sit in the tank for a few days to let the chlorine escape and make the water suitable for fish. Aerating the water with air pumps can greatly help this process. Alternatively, if time is of concern then the water can also be treated with commercially available chemicals such as sodium thiosulphate (2). Once initially dealt with, chlorine concentrations do not need to be monitored unless more tap water is added when water changes.
Carbon dioxide
Dissolved Oxygen
For warm water fishes, the recommended level of dissolved oxygen is 4 to 5 mg per litre. Dissolved oxygen may be a crucial to monitor as low dissolved oxygen levels may stunt growth, affect feeding and can lead to hypoxia. This causes high levels of stress for the fish and cellular damage (1). To prevent this, most aquarium systems have a aerators. The capacity and amount of aerators required depends on the volume of water and is always indicated by the product’s description. So as long as ample aeration is occurring in the system, the use of analog dissolved oxygen monitors may be omitted as they are expensive and inessential for home users keeping ornamental fish.

Sensors
Temperature Sensor
An appropirate temperature sensor would be the DS18b20 waterproof temperature sensor, this is waterproof and is compatible to use with Arduino IDE. It requires a breadboard / soldering of wires (to be done at a later stage). This temperature sensor has three wires which all connect to a different pin in the Arduino. The black pin connects to a ground port, red pin connects to a VCC port which is powered by either 5v or 3.3v power supply. The yellow pin is connected to any chosen digital IO pin on the Arduino. The connections can be made using a breadboard or by using jumper wires with soldering of the loose wires on the temeprature sensor to the jumper wires (and then connecting the jumper wires to the Arduino itself). The coding with this sensor is relatively straightforward and involves using the libraries <OneWire.h> and <DallasTemperature.h>. A simple call to an in built method of the libraries after proper setting up (the call is sensors.requestTemperatures()) checks the temperature of the water the temperature sensor is inside and the values can be retrieved by calling: sensors.getTempCByIndex(0).

PH Sensor
An appropirate PH sensor would be the Gravity analog PH sensor kit. This contains a PH probe and a signal conversion board. The PH probe is what is immersed in the liquid which is being tested for it's PH value whereas the signal conversion board acts like a communication mechanism between the PH sensor and the Arduino board, sending the read PH values to the Arduino. The wiring of this is as follows: the blue wire on the image on the right should be connected to any digital IO pin on the Arduino, the red wire requires to be connected to a 5V VCC pin and the last black wire should be connected to a ground pin. The connections are easier to be made using female to male jumper wires. The code works by setting the chosen digital IO pin to HIGH and LOW and using a formula to calculate the PH based on the transmitters response.

Turbidity Sensor
This is a sensor to check the "clearness" of the water. There are two types of turbidity sensors which are linked below, both principly work the same. Turbidity is measured in terms of NTU which is a "Nephelometric Turbidity Unit". The lower this NTU value the better the water quality, higher NTU values mean worse water quality as there is an increased scattering of light (more particples and dirt in the water). The connections are simple but differ based on the turbidity sensor purchased in principle it requires a 5V VCC pin, a ground pin and any digital IO pin on the Arduino. The code works by running a for loop over 800 iterations to read the required sensor input which the result of the input is added to another local variable. After this the value is converted to NTU and can be viewed on the serial monitor or an external LCD (optional, not for our project).

Ammonia Sensor
The most suitable sensor to detect any ammonia presence in the fish water is the Mq137 ammonia sensor. Before using this sensor it must be calibrated to the environment around it therefore using an external program to do so. The wiring is simple in principle it requires a 5V VCC pin on the arduino to be connected to the VCC pin on the sensor, a ground pin on the arduino to be connected to the GND pin on the sensor and any digital IO pin on the Arduino to be connected to the AO pin on the sensor. A 47k ohm resistor is also needed to be used for the connection between the AO pin on the sensor and any digital IO pin. The code works by taking in the parameters set above after calibration and thereafter uses a logarithmic formula to calulate the PPM (parts per million) of ammonia present in the air around (also can measure ammonia in water, it is important to not put the sensor underwater).

Actuators
Heater Plate
This is need for the "actuator" side of our autoamted fish care system. This heater plate will turn on whenever necessary (when the temperature of the aquarium is detected to be too high) and thereafter it will stay on until the temperature of the aquarium has reached the desired temperature. This works simply by connecting to an external 12v power source (so just a plug point), this will have to be controlled (turned on or off) by an external switch connected to the arduino to control this. It cannot be connected directly to the Arduino as the Arduino only supports providing power upto 5v hence this heater plate requires 12v. The arduino code will be simple logic ie (if sensors.getTempCByIndex(0) <= threshold1 THEN switch.on() and thereafter if sensors.getTempCByIndex(0) >= threshold2 THEN switch.off()).

Servo motor
For the precise quantity of food to be dispensed a part must be moving for a certain amount of time to push or release the food into the water, and then stop. After some research it appear that a common way to achieve that is with an Archimedes screw rotated by a servo motor for a specific amount of time. This method as several advantages: it provides a continuous flow of food, such that any desired quantity can be precisely delivered, it only takes a small amount of space, and is relatively easy to implement as 3d models of Archimedes screws compatible with servo motors are available online. The servo motor can be directly connected to an Arduino via a 5V VCC and a ground pin. It is controlled very precisely, which allows for a very specific amount of food to be dispensed. It then suffices to write a line of code that sends power to the motor pin for a certain amount of time every x seconds, which are to be determined based on parameters given by the user (number of fishes, size of fishes...).

Microcontroller and communication
Microcontroller
A microcontroller is needed to activate the actuators based on the data received by the sensors and the user. A very popular line of products for this kind of projects is the Arduino line, which provides rather cheap microcontrollers that are very modular and compatible with plenty of sensors and actuators via serial communication with pins. The most popular Arduino model is the UNO Rev3 which is based on a ATmega328P processor with 14 digital and 6 analog inputs/outputs. However it does not have built-in wi-fi, so another module such as the ESP8266 must be connected to it. Another option would be the Arduino Uno R4, which directly has wi-fi connectivity. Both products are compatible with the Arduino IDE software that is used for development, with a simple language to control the pins.

Wi-fi module
In order to communicate with the mobile app the device must have a way to send and receive the data. A common way to achieve this with an Arduino is with the use of an ESP8266 module for Arduino. This modules enables wi-fi transmission and then transmits the data via serial communication to the microcontroller. Wi-fi is ideal for our user target group because personal fish tanks are generally in houses, meaning that a router will always be nearby to send the data over the internet. Another option would be to directly use an Arduino model that has wi-fi connection integrated, such as the Arduino Uno R4.

State Machine Diagram
On the right hand side we see our initial approach at our automated aquarium manager represented clearly using a state machine diagram. In this initially the manager is off and when it is turned on (assuming there is power) it sends a notification to the user that it is on. It stays in a so called "checking state" in which the sensors are continuosly run until an issue is detected. For example if the temperature is too low, it exists the checking state (which turns off all the sensors), and enters the heater on state which turns on the heaters and only exits this state when the target temperature is reached (the event temphigh is met) then it turns off the heater. Similarly whenever the ph is too low it goes to the PHLow state subclassed in PHControl and releases the required chemicals to improve the ph and thereafter it goes back to the checking state (similar for PHHigh). Whenever there is high ammonia concentration detected it sends a notification to the user about this so it can be resolved as soon as possible in the NotifyAmmonia state subclassed in Notify User, once this notification is sent it goes back to the checking state again (similar for NotifyDirt). It ensures these NotifyUser substates are only entered if the notification hasn't already been sent (otherwise it will keep sending the same notification again). In the do/ in the checking state we check if the user has resolved the notification about high ammonia / dirt until we activate sending a notificiation for that issue again.
Sources With Summaries
Automated Monitoring System for the Fish Farm Aquaculture Environment
The paper introduces a method for fish farmers to actively control their farm. They introduce a problem of waste, unnecessarily created by a lack of monitoring their fish. The waste can be reduced by actively tracking the fish and feeding when needed. They also state that, for optimal farming, the conditions in such a tank should be kept at certain rates. The team establishes a device to monitor the data acquired, using simple but accurate sensors. They describe a way to measure the most important values and how they created a system available for the user. They create a software program that runs on android devices to give the farmers access to the results, and create a space where the farmers can change certain values based on the fish their needs. The paper doesn’t specifically state for which levels the system is made, and what would be optimal for certain species. The energy management of the system is very efficient, and because of the WIFI implementation they created an accessible system.

Design and implementation of a smart monitoring system for water quality of fish farms
The paper focusses on the creation of a monitoring system for fish farms. The authors try to give real time information to the farmer via a mobile app. They see the rapid change in the health and agriculture sector towards a fully monitored and perfected system. The authors use an Arduino UNO and a pH and temperature sensor to monitor the values in the tanks. The user can use his phone with a Bluetooth connection to connect and get the real time information on their mobile device. There are some major improvements that could be made compared to this project. The information is quite limited and could be extended on. Also we could try to implement a more autonomous system that does certain tasks like changing pH or giving food. The system could also be upgraded to be more up to date and accessible.

Aquarium Monitoring System Using Sensors
https://ajast.net/data/uploads/10119.pdf
This paper addresses the issue of fish tank maintenance time for homeowners and possible inconveniences it causes. The solution proposed is a fully automatic system that feeds the fish, monitors and displays temperature and a water circulating system with the additional function of heating that controls water temperature. This process of heating water when its circulating through pipes instead of directly adding a heater to the tank water allows for better and consistent temperature control. The fish feeder works with a simple servo motor and container controlled by an Arduino.
