Solar Powered Auto Irrigation System
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
