Control of Irrigation System Using GSM Technology

Abstract

This paper proposes an irrigation system using microcontroller, GSM module and a moisture sensor, which helps in providing an effective and reliable irrigation system, thereby saving the time of the farmers. The microcontroller gets the input from GSM module and moisture sensor to operate the motor and appropriate solenoid valves to feed water only to the preferred area of the agricultural field. The input to the GSM module is given as messages from the farmer. The presence of solenoid valves reduces the number of labour required to be in the field to feed water to individual areas. The farmer can remotely operate the irrigation system and save water by automatically switching off the motor whenever the moisture level of the soil exceeds the critical value. The farmer can also switch off the motor by sending message to GSM module thus providing flexibility.
