Abstract: In this paper we present a prototype for automatic controlling and remote accessing of irrigation motor. Prototype includes sensor node, controller node and mobile phone. In sensor node, soil moisture sensor and wireless transceiver is integrated with ARM cortex microcontroller. In controller node, GSM module, wireless transceiver, keypad, LCD display and a motor is integrated with ARM7 microcontroller. The sensor node can be deployed in irrigation field for sensing soil moisture and the sensed data is sent to controller node. On receiving sensor value, the controller node checks it with required soil moisture value. When soil moisture in irrigation field is not up to the required level then the motor is switched on to irrigate associated agriculture field and alert message is send to registered mobile phone.The controller node has navigation keys to set the mode of operation and an LCD display to view sensor data. The prototype is tested by abstracting three pots containing soils with different moisture level as irrigation fields. Results show the proposed prototype is effective in automatic controlling and remote accessing of irrigation motor based on the feedback of soil moisture sensor and commands from mobile phone.
