Monitoring and control of greenhouse environment play an important role in greenhouse production and management. To monitor the greenhouse environment parameters effectively, it is necessary to design a measurement and control system. The objective of this project is to design a simple, easy to install, microcontroller-based circuit to monitor and record the values of temperature, humidity, soil moisture and sunlight of the natural environment that are continuously modified and controlled in order optimize them to achieve maximum plant growth and yield.
Greenhouse monitoring and controlling project is used to measure the various parameters like Temperature, Light Intensity, Carbon-Monoxide and Soil moisture, and display these parameter on a LCD. Given parameters are sensed by respective sensors. Sensor output is analog and given to ADC pin of microcontroller. Microcontroller controls these parameters and keeps them at some predefined levels using relay. These relays can be connected to Fan/Heater.
This project is designed with microcontroller AVR, 16 * 2 LCD, Internal ADC, Temperature Sensor, Light Sensor, Carbon monoxide & soil moisture sensor. Sensors used to sense atmospheric conditions according their parametric structure and material, these sensed signals are inputted to the microcontroller. A 20 * 4 LCD, connected to microcontroller through communication interface, displays information regarding the person that has been already fed into it.
