An Embedded Arduino based LPG Detection System with SMS Alert and Automatic Gas Shut Off

Abstract

The level of technological advancement which engendered enhanced transportation of Liquefied Petroleum Gas (LPG) has, to a large extent, solved the problem of energy demand. Unfortunately, in doing this, it brought about concomitant risk- damage to the pipes as a result of human errors, natural disasters, and acts of vandalism. This paper addresses the issue of gas leakage and proposes a leakage detection system using an MQ 2 gas sensor, a buzzer, and a GSM module. A response mechanism which shut off the supply of gas when the level of leakage seems not to reduce.
