Abstract
Artificial supply of water to land, to maintain or increase yields of food crops, a critical element of modern agriculture. Irrigation can compensate for the naturally variable rate and volume of rain. Water is pumped using motors from natural ponds, lakes, streams, and wells.
In the present agriculture trend the motors in fields are monitored manually. The Farmer goes to the field every time, checks the status of the motor, Inspects area irrigated to ensure adequate soaking and prevent waste of water and checks the water level in the bore well.
This system is developed for the farmer to monitor the motor and the water level in the bore well or well and the area irrigated, from his home or wherever he was.
In this system, the farmer can control the motor in his field through his mobile phone or a unit which consists of keypad for user interface. This unit consists of a LCD to display the motor status from time to time.
The unit on the other side, which is placed in the field receives commands from the farmer’s mobile unit and works as per. In case of motor failure or any other faults such as overload, fuse blow out, the system will stop the motor and send a warning signal to the main unit (unit which farmer carries).
This control system stops the motor even in case of adverse environmental conditions and reports the status to the main unit. The Environmental conditions are monitored using sensors and the information is sent to the main unit.
The main unit should be designed in a very user friendly manner so that even an illiterate person can operate the unit.
Advantages:
The numerous advantages with this system are:
• No need of going to the field to just control the motor .He can operate it from the place where he is and continue in other works, thus saving time
• Because the motor is not monitored manually for faults there is no chance of any accident or shock in any conditions
• In case of power supply fluctuations, farmer can immediately switch off the motor by sending appropriate command, thus avoiding any loss.
• Since the unit is controlled automatically the unit is less prone to manual errors
• No need to employ a separate labor to check the conditions of the motor thus saving the cost and the faults are detected automatically
