The motivation for this project came from the farmers working in the farm lands are mostly dependent on the rains and bore wells for irrigation of the land .even if the farm land has a water pump, manual introversion by farmers is required to turn the pump on and off .the aim of our project is to minimize the manual intervention by the farmer Automatic plant irrigation system using solar panel will serve the irrigation is the only when there is not enough moisture in the soil. And the sensor decided when the pump should turn on and off. Here the pump is run by solar energy which is saved in the battery. It saves lot of time for farmers.
