Introduction

Problem Statement and Objectives

Home automation systems, including automatic lighting and temperature control have recently become widely adopted in modern smart homes, to save energy and serve as a convenient alternative to manual controls. This promotes sustainability and convenience while also serving the needs of people who are unable to manage their homes independently, such as the elderly or disabled. Though the market for home automation is highly saturated with companies such as Google, Philips and Amazon designing sophisticated, there is a lack of automation systems for greenhouses and gardens. While they exist, our group believes that there is significant potential and a gap in the market for such a series of products, which monitor and automatically control certain parameters in gardens and greenhouses such that plants and crops remain healthy in the absence of human intervention.

A holistic approach that monitors parameters such as temperature, carbon dioxide concentrations, soil moisture, and light, can be used to control a series of actuators that act such that each of the parameters are optimized for the crops grown by the user. To accompany the system, a smartphone app can also be developed such that the user can customize the settings depending on their crops. A more thorough description of the features and functionality of the product is given in subsequent sections of this page. The problem statement or main objective of this project is “to design a series of products that demonstrate the possibility of the automation of greenhouses, promoting sustainability and convenience in agricultural domains”.  

Users and Target Audience

The target users of our greenhouse automation system are home gardeners. These people usually operate on a smaller scale, with planting within their personal gardens or within their house. These will require careful maintenance of their ecosystem making them a prime target audience.

Schools/Educational institutions are also a target audience for our system. They might make smaller versions of greenhouses in buildings for educational purposes. In these cases, an automated system could prove to be useful to maintain those projects.

Community garden groups are also a target audience as those gardens might require an automated system to be properly maintained as well. Since sometimes people might not always be able to properly maintain their plants on time.

The planned automation system will not target farmers and large-scale agricultural operations due to the sheer size of the needed coverage. This will likely result in very expensive tools to maintain the workspace.

Requirements of Users

The user requirements of an automated greenhouse system are customizable greenhouses fitted with multiple devices to control the greenhouse environment. Sensors with the ability to measure CO2, humidity, temperature, soil moisture, and soil pH levels are required as an input to the system. Actuators to control the Windows, irrigation systems and heating systems are required to control the environment based on decisions made by the system. The system should set certain parameters such as temperature, soil moisture, humidity, and CO2 levels, based on the plants planted inside the greenhouse. The system then can use predicted weather patterns to further improve the efficiency of the greenhouse.

Smart and efficient greenhouses: a systematic literature review in the agronomic, computational, and energy scope

The article "Smart and Efficient Greenhouses: A Systematic Literature Review in the Agronomic, Computational, and Energy Scope" presents a comprehensive analysis of controlled environment agriculture, focusing on the integration of intelligent computational techniques and energy efficiency in greenhouse cultivation.

the researchers identified over 2,000 scientific publications within a 5 to 10-year timeframe and arrowed the publications down to just 66.

The application of automation and control techniques in greenhouses began in the 50s, where temperature control was performed by thermostats. Subsequently, there was a great advance from the structural design to the technological aspects that make up the system, seeking improvement to allow the control of the parameters of temperature and relative humidity, solar radiation, CO2 concentration, ventilation, and fertigation.

Furthermore, results relevant to the project are

- The correct use of land and the efficient use of water and electrical resources stand out. The authors emphasize the need for mechanisms that optimize these environments. However, the use of control systems for these spaces and environments is relatively complex, due to the multiple variables involved and the interdependence between them.

- several control strategies for greenhouses. These strategies aim to make the environment ideal for crops, considering energy savings. Among them, we can mention: mathematical modeling; experimental studies and simulations; control of parameters and components; the use of algorithms and computational intelligence techniques

- The authors highlight that the cost of electricity is the second highest cost in cultivation in controlled environments, with the labor costs being the most expensive.

- aiming to find optimal conditions for the growth and development of seedlings in a greenhouse environment. The authors conclude that the application of IoT associated with product traceability promotes

Greenhouse automation system | Automated greenhouses | Priva

A company called Priva has recently developed a large-scale automation system which enables irrigation, lighting, climate control and even nutrients. These are all essential aspects of crop health and growth, and can be controlled using a smartphone app. While their target audience seems to be larger agricultural businesses, the concepts and ideas are relatively similar to our own project. The main goal is to automate the process such that energy can be saved, mistakes are made less often and to promote convenience for end users. The company seems to be targeting large businesses that specialize in farming and agriculture, and therefore the requirements are bound to be different. In our project, we will take inspiration from such existing state-of-the-art systems and build upon it to ensure user-friendliness, convenience for consumers (especially individual gardeners and greenhouse owners) and sustainability.

Greenhouse Automation - DutchGreenhouses

A competing brand named DutchGreenhouses has also developed a similar greenhouse automation system.

Greenhouse Automation - Logiqs B.V.

The brand Logiqs B.V. has a very innovative approach to greenhouse automation. It consists of “rolling benches” that move around the greenhouse upon which crops are grown. The company claims that this state-of-the-art technique is highly effective and efficient because physically moving plants across climate zones is far more energy-efficient compared to actively changing the temperature. They also believe that this creates better working conditions and ensures cleanliness due to automated cleaning procedures. The benches are also fitted with automatic irrigation with precise control over the frequency and amount of water and nutrients to be fed to the crops.

A Review of Greenhouse Climate Control and Automation Systems in Tropical Regions

This paper by Shamshiri et al explores greenhouse climate control and its effectiveness. The authors also research the ideal levels of temperature and relative humidity to maintain healthy crops. For example, there is a table providing the ideal temperature and humidity conditions during each growth stage for tomato crops. This information is valuable for designers of greenhouse automation systems as they can design the systems to maintain by default the ideal parameters for optimal crop growth. Users can also refer to this information and customize their systems to ensure peak yield of their crops.
