Abstract

This paper presents the design and construction of an SMS based Gas Leakage Alert System. Two gas sensors (MQ-6) were used to detect gas leakages in a particular location; their outputs are then interfaced with an 8051 microcontroller programmed in assembly language. A dedicated GSM phone with a line is connected through relays to the output of the microcontroller. The GSM phone is configured to send gas leakage alerts in the form of a short message service (SMS) message indicating the location to another GSM phone to enable prompt necessary action. The system enables monitoring of gas leakages in remote locations and thereby leads to a faster response time in the events of a leakage condition.
