Abstract
Agriculture is a source of livelihood of majority Indians and great impact on the economics of the country. In dry areas or in case of inadequate rainfall, irrigation becomes difficult. A low cost alternative solution for efficient water management currently in use is drip irrigation system that consists of a pressure controller to turn on and off the control valve, which in-turn helps the farmers by managing the water supply to the crop fields and further maintains the moisture level of soil. When the soil is dry condition the soil moisture sensor measure the resistance and send the signal to relay to actuate the solenoid valve. If solenoid valve open the pump is ON then the flow can happen by pressure controller, whereas the soil is wet condition, the solenoid valve closes. Based on this technique, automated the irrigation system without wire and wireless technology using pressure controller.
