LPG Leakage Detection and Alert Indication System for Domestic and Commercial Use

In recent years, domestic fire cases due to Liquid Petroleum Gas (LPG) leakage are happening frequently and such accidents are increasing every day. If a person is in a hurry and sometimes due to negligence the gas regulator may not fit properly or have not switched off the gas regulator properly, then there might be chances of accidents due to Liquid Petroleum Gas leakage. The Liquid Petroleum Gas leakage detection and alert indication system is very helpful in the cases when no one is present in the house with Liquid Petroleum Gas cylinders in it. Now a days Liquid Petroleum Gas cylinders are not only used for the cooking but they are widely used for water heating or as a gas for the vehicles. Liquid Petroleum Gas leakage detection and alert indication system is required in all these situations to provide safety and avoid house fire accidents. The developed Liquid Petroleum Gas leakage detection and alert indication system is light weight compact, based on Arduino and by using Global System for Mobile communication modem it sends alert Short Message Service /Call indication on mobile. Global System for Mobile (GSM) communication modem sends Short Message Service /Call to the user when the Liquid Petroleum Gas leakage goes beyond the set limit of threshold level. When Liquid Petroleum Gas is detected, the system not only sends an Short Message Service/Call alert but it also turns on the Light Emitting Diode (LED) for visual indication and buzzer to alert the person which is in vicinity of the system.
