The main idea of gas leakage detection is to implement the security system for detection of gas leakage in closed environment. In present scenario, there are many criteria which are related to gas leakage which affects an innocent people lives and property damage. Implementation of this alert system can be useful for companies, houses, which can save lives of people. In this work, SIM900 (GSM module) is used to perform the chosen task by interfacing Gas sensor (MQ5), Buzzer, Arduino UNO, Stepper Motor(5V) and LCD to display. Initially when there is a leak, the Gas sensor detects it using MQ5 and sound alarm is produced automatically and the leakage of gas is controlled. Also, an SMS based system is setup using GSM Module which sends 3 alerts (messages) to the specified mobile number. Not only detection of gas leakage but also stopping the leakage is equally essential to detection. This project provides an effective in cost and highly accuracy, which not only detect gas leakage but also alerting the people (sound alarm) and turn off main power and gas supplies, and send an SMS. In despite to provide high accuracy, gas sensor MQ-5 has been used and this can be used in application of chemical and hazardous industries where there is a consecutive monitoring of gas leaks. By using different types of gas sensors for various gas, used to identify leaks for every kind of gases. Thus, on designing this project our ultimate aim is to automatically detect and stop leakage in vulnerable premises.
