Abstract: The farmers working in the farm lands are solely dependent on the rains and bore wells for irrigation. Even if the farmland has a water-pump, manual intervention by the farmers is required to turn the pump ON/OFF whenever needed. Therefore using an Android application which helps the farmer to ON/OFF the motor without his physical presence in the field. This paper has real time sensing and control of an irrigation system. When the condition of water in the agricultural farm is abnormal then the system automatically switches OFF. Based on the soil moisture, through relay the pumping motor will be automatically switch on or off which saves the water and on the other hand the plant can get most appropriate water level which increases the productivity of the crop. Using GSM (Global System for Mobile communication) technology which is used to inform the user about the exact condition of the field. This information is passed onto the user request in the form of SMS (Short Message Service). The proposed system provides uniform and required water level for the agricultural farm and it avoids water wastage.
