GSM Based Real-Time Automation of Irrigation System using 8051 Microcontroller


At the present era, the farmers have been using irrigation technique in India through the manual control in which the farmers irrigate the land at the regular intervals. This process sometimes consumes more water or sometimes farmer may forget to switch ON the irrigation system due to which the crops get dried. Water deficiency can be detrimental to plants before visible wilting occurs. Slowed growth rate, lighter weight fruit follows slight water deficiency.

This problem can be rectified by using automatic irrigation system using 8051 microcontroller. This automatic system can be operated remotely by the farmer, if he desires to water the crop field. The automatic irrigation system itself switches ON to watering the crop field at regular intervals of time without the involvement of the farmer. The farmer knows the ON/OFF status of the irrigation system by receiving SMS, which is automatically sent by the irrigation system. The farmer can send two formats of SMS as mode 1 and mode2. In mode1 format the farmer can change the water irrigation time intervals. In mode2 format he can directly switch ON the irrigation system whenever the needs it. A water level indicator system will signal the microcontroller system that required water content is supplied to the field or not. By checking that status signal the microcontroller system automatically switch off the irrigation system. The entire Microcontroller system runs under battery power, hence it monitors the power failures. According to the power failure the water irrigation system will be automated.

In this project, DC motor along with microcontroller circuitry shows the automatic irrigation system. The GSM modem is used to receive the message from the farmer and also used to send the status of irrigation system via SMS. A water level indicator circuit is used to know, that the required water is supplied to the field or not. A real time clock is used to get time and according to that microcontroller system compares it switch ON the irrigation system at regular intervals.
