Main Supply Detection and Intimation by Using Arduino and GSM Module

M. Narendra Kumar, G. V. Naveena Reddy

Abstract: Now-a-days, various automatic change over switches have been available and implemented in various disciplines. But its implementation and cost is high. In order to overcome this drawback, we are implementing the wireless communication technique, GSM. GSM (Global system for mobile communication) is vastly used because of its simplicity in both transmitter and receiver design. It can operate at 900 or 1800MHz band, faster, more reliable and globally network. The proposed module, is capable of sending calls and SMS in the presence and absence of main supply. Arduino Uno is the heart of our system, which controls the overall operation. System always alerts the operator on the occurrence of power problems i. e, on and off of power supply by sending a call and message to him.
