Automated Greenhouse Monitoring System
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryAs to summarize the project we can say that a greenhouse is a building with glass walls and a glass roof. Greenhouses are used to grow plants, tropical flowers. A greenhouse stays warm inside, even during the winter. In the daytime, sunlight shines into the greenhouse and warms the plants and air inside. This particular greenhouse is automated in terms of sensors taking data and functioning the related actuators accordingly.
Project ObjectivesIn this project our main objective is to create a feasible environment for plants to grow inside a green house through automated controlling and monitoring of different parameters including the intensity of light, temperature and soil. Generally, The primary objective of greenhouses is to produce agricultural products outside the cultivation season. They offer a suitable microclimate for plants and make possible growth and fruiting, where it is not possible in open fields. This is why a greenhouse is also known as a “controlled environment greenhouse”. The main objective of a greenhouse is to enable you to create the specific environment for the needs of your plants. For example, you can grow tomatoes in a heated greenhouse in the winter. Or, you can use a covering with a lower light transmission for plants that require a shady location. You can control the light, temperature, humidity, watering, etc. with the proper equipment. You can also use it as a location to protect frost sensitive plants in the winter. Many people are using greenhouses to grow a year round food supply for their family. They are a great place for aquaponic or hydroponic systems. Many people are using them for food production and ornamentals as well. In conclusion, the uses are varied, but the main objective is to control the environment.
Project Implementation MethodIn this project we are creating a greenhouse frame that has to regulate the temperature, humidity and light intensity inside the greenhouse box. All the parameters are measured through various sensors and are linked to the microcontroller. The ambient temperature sensor allows us to start the fan and to drive a servomotor to open the window when the internal temperature is above the temperature set point. So, if the temperature descends under the temperature set point, the fan is stopped and the window is closed. Furthermore, a lamp is switched on to warm the plantation. The soil moisture sensor allows to drive the water pump for the watering system when the soil is too dry.
The Stepwise construction will contains the following steps:
1) The construction of the main glass frame.
2) Location selection and installation of equipment like fans, water pump, and tubes, micro-controller, sensors positiong, etc.
3) The soil setup in a tray with some plants, vegetables or flowers.
4) Implementation of code through microcontroller to take all the input data through various sensors.
5) Implement the requirement of the working for the feasible enviroment inside the greenhouse by taking real-time data of sensors and monitor them.
6) Test the project's automation in actual time and real scenario.
After that finalize to entire hardware structure in the representable form and in better shape with all the required aesthetical work and further designing.
Benefits of the ProjectA greenhouse is a safe haven for plants and we can conclude the benefits of constructing a greenhouse in the following points:
1) It reduces the accessibility of insects and animals that have the potential to damage or destroy your plants.
2) It reduces exposure to extreme weather conditions such as heavy rain fall
3) Wind Effect is also minimized
4) Protection from storms.
5) Protection from animals.
6) It also protect the plants from low level precipitation.
We can improvise the usability of the greenhouses by two more methods.
If we are constructing the greenhouse in a remote area then the power supply would be an issue so for that renewable sources such as Solar Energy would be used to power up the greenhouse and to actuate all the electronics.
Secondly, we can take this to the cloud so that we can have remote access to monitoring data of our greenhouse through web or application.
Technical Details of Final DeliverableThe project will be an automated greenhouse monitoring system in which all the parameters which are used to create a feasible environment and stabilize it to grow plantation.
The final state of the deliverable project will be a fully functioning automated greenhouse system with all the necessary data being displayed on a LCD screen or on web portal.
The various sensors including humidity sensor, temperature sensor, light sensor will be connected to the microcontroller and their real time input will be feed into it. The desired values for the feasible environment inside the greenhouse has already been fed into the microcontroller for comparision and the microcontroller automatically detects which value of sensor is below or over the desired value, then the actuator function in accordance with that input. Like if the temperature is risen above the set point, then the fan will turn on inside the greenhouse and window ventilator will be open and as soon as the temperatures meets the desired value then the fans turns off and the window closes. Same goes with the soil moisture indicator as well. If the humidity sensors pick less humid soil then it activates the water pump to flow water through tubes to the soil for a specific value in millilitres or litres and then after a specific time that pump stops.
Thepower backup solutionfor our off-grid system will be consiting of a Solar PV Panel with a set of batteries so that the entire greenhouse could easily be ran on that sufficient amout of power backup.
