Development of LPG gas detection and control system

Date : Sep 2017 - Aug 2018

Gas leakages resulting into fatal inferno has become a serious problem in household and other areas where household gas is handled and used. Gas leakage leads to various accidents resulting in financial loss as well as human injuries and/or loss. The work aims at designing a system that detects gas leakage and alerts the subscriber through sms and status display besides turning off the gas supply valve as a primary safety measure. The shutting off of the supply valve stops further gas to prevent fire outbreak arising from attempt at igniting of the cooker. The system more like a first Aid, automatically uses a normally closed solenoid valve for the shutting off of the gas valve before calling for help via visual display and audible alarm to those within the environment. The aim of this project is to present such a design that can automatically detect and stop gas leakage in vulnerable premises. In particular gas sensor has been used which has high sensitivity for propane (C3H8) and butane (C4H10). Gas leakage system consists of GSM (Global System for mobile communications) module, which warns by sending SMS. However, the former gas leakage system cannot react in time. This work will minimize injuries/losses occasioned by explosions due to gas leakages and improve safety of life and property while using domestic cooking gas.
