ABSTRACT
This project presents the design and implementation of gas detection system using GSM network. Gas leakage is a major problem with industrial sector, residential premises and gas powered vehicles like CNG (Compressed Natural Gas) buses, cars, etc. One of the preventive methods to stop accidents associated with the gas leakage is to install a gas leakage detection device at vulnerable places. The aim of this project is to develop such a device that can automatically detect gas leakages in vulnerable areas and as well alert the owner anywhere in the world via GSM network. The system detects the leakage of the LPG (Liquefied Petroleum Gas) using MQ6 gas sensor and uses the GSM phone to alert the person about the gas leakage via Call. When the LPG concentration in the air exceeds a certain level, the gas sensor senses the gas leakage and the output of the sensor goes LOW. This is detected by the microcontroller, and the system then alerts the customer by calling a specified mobile-phone number.
Keywords: GSM (Global System for Mobile Communications), LPG (Liquefied Petroleum Gas), Gas Sensor MQ-5, LCD (Liquid Crystal Display), LED (Light Emitting Diode).
