Microcontroller Based Greenhouse Monitoring and Controlling System

Abstract:

By using a low cost more efficient programmable module to detect the climatic behavior inside the greenhouse and controlling the parameters according to their crop production need, through various techniques with the use of board Ardunio UNO. The parameters that need optimization are the water content of the soil, the light intensity coming from the natural or artificial sources, the temperature and humidity of the field area. To overcome such challenges, this greenhouse monitoring and control system comes to rescue. This project demonstrates the design and implementation of a various sensors for greenhouse environment monitoring and controlling. This greenhouse control system is powered by Arduino UNO which consists of DHT11 sensor, soil moisture sensor, LDR sensor, LCD display module, DC fan, led and pump. Temperature sensor senses the level of temperature, if it goes high DC fans gets on and when the temperature goes low the fan gets off. Soil moisture sensor, senses the water level as the level decreases the pumps gets on. In the absence of light, the LDR sensor senses and the led start glowing. And all the data is uploaded on thingspeak. By this way it will become easy to monitor and control the system.
