Solar Powered Auto irrigation System

The main aim of this project is to implement solar based automatic irrigation system for switching the pumping motor depends on the signal from soil moisture sensor. By receiving the signals from the sensor, microcontroller performs the switching of pump using relay.


The Auto irrigation system of this system uses soil moisture sensor to detect the moisture level and 4X4 keypad for various crops control. When the moisture content of the soil is reduced then the sensor sends detected value to the microcontroller. Then the water pump is automatically ON according to the moisture level. The main aim of this paper is to reduce the human intervention for farmers and use solar energy for irrigation purpose. The entire system controlled by the PIC microcontroller.
