INTELLIGENT CONTROL OF IRRIGATION PUMPSETS USING RAINSENSOR

This paper deals with microcontroller based automatic control of irrigation pump sets using the application of rain sensor. If the field has to be irrigated for 3 hrs(say) then the timer is set for 3 hrs using microcontroller and hence motor runs automatically only for 3 hrs per day . Hence there is no need for the farmer to look after his field being in the farm for the whole day. In addition to that rain sensor has been used to switch off the motor when ever it rains to save the power.
