Automatic Greenhouse Environment Monitoring and Controlling System

Abstract

Agriculture is a most important part of our human life and the condition around the agriculture environment is changes within time. In the greenhouse environment we can change as per the growth of plants. The conditions around the greenhouse have a greater impact on crop agriculture. Temperature, humidity, lighting intensity, the moisture content of the soil, various gases present in the greenhouse environment and the amount of CO2 in the greenhouse are the most important environmental factors that influence the quality and productivity of the plant growth. A lot of research has been carried out in order to be able to develop a monitoring and controlling of greenhouse environment that will help in solving the main problems relating to agriculture which is to enable the increase in the productivity of crops. Green house farming is the unique farm practice of growing crops within a controlled environment weather and climate condition controlling is the prime concept of greenhouse. The main aim of this project is to design a simple, low cost, Arduino based system to monitor the values of environmental parameters and that are controlled in order to achieve optimum plant growth and yield. DHT11 sensor, Soil Moisture sensor, humidity sensor, gas sensor are the main sensors used in this project which give the exact value of temperature, humidity, water content, light intensity respectively. By using Arduino if the preset value of any parameter is exceed low or high then they can control actuators (exhaust fan, water pump, heating light, buzzer and motor pump) and all this parameters values and condition of the actuators are display on the LCD display. That will help to growth of the plant, The result obtained was a fully functioning system that was set to monitor the greenhouse environment.
