India is an agriculture country and all its resources depend upon the water, and water is becoming one of the most precise natural resources. Irrigation may be defined as the process of artificially supplying water to soil for raising crops. A solar panel is used to charge the battery and by using inverter it is converted into AC. The field humidity is prime parameter considered for plantation of different plants. It is controlled by sensors, for minimum and maximum humidity. The field is irrigated by a separate valve. The valves are controlled by the PLC. Through feedback control mechanism, humidity of the fields is maintained at the certain level. In PLC based drip irrigation system we control the percentage of moisture in the soil. The developed irrigation system removes the need for workmanship for flooding irrigation. So we use PLC programming if there is immense need of water to the crop in order to get maximum profit with minimum cost.
