LPG Gas Leakage Detection and Prevention System

Abstract

Gas leakage has been a major concern in recent times. Though its usage has been extended in various industries, a small unattended leakage can lead to catastrophic damage. The objective of this project is to present the design of a cost effective automatic alarming system, which can detect and prevent liquefied petroleum gas leakage in various premises. This system alerts the user by sending him an SMS and alerting the neighbors by buzzer alarm after the gas leaks above setpoint1.The stepper motor is used to close the gas pipe valves. To reduce risks to human life, main power supply is cut off, if the gas leakage goes above setpoint2. This device ensures safety and prevents suffocation and explosion due to gas leakage. This project is implemented using ARM 7 processor and simulated using keil software.
