Abstract :

In this undertaking we utilize sunlight based vitality which is utilized to work the watering system pump. The circuit involves sensor parts manufactured utilizing operation amp IC. Operation amp's are designed here as a comparator. Two hardened copper wires are embedded in the dirt to sense whether the dirt is wet or dry. Microcontroller is utilized to control the entire framework by checking the sensors and when sensors sense dry state of soil, then the controller will send charge to hand-off driver IC the contacts of which are utilized to switch on the engine and will switch off the engine when the dirt is in wet condition.
