It has been seen that, in the agriculture, wastage of water and valve controlling is one of the major concern. At present it is operated manually which leads to great man power requirement. Also adequate and required supply of water is needed in agriculture. Along with these concerns, fluctuations in electricity lead to damage the motor permanently. So we have made an attempt to design a system, which would control the valve action based on the sensors output through GSM. Along with this it also prevents permanent damage of motor from fluctuations in electricity. The main aim of the project is to read the sensors output and to control the valves through the GSM technology. Input signal 230v ac given to the transformer of 12vdc and 12v dc signal is send to microcontroller. Status of the field is sent through the GSM based on the output of the sensors. Depending on this status, valve controlling action is performed. After the adequate supply of water, valves are closed automatically depending on the updated status of the sensors. In this project, we have also improved on automatic action taken to control the valve action in case of GSM facility failure.
