Abstract – In this paper, we have proposed a Smart Gas Leakage Detection with Monitoring and automatic safety system. Nowadays, people are facing huge side effects due to gas leaks. As a solution, we have developed a gas leakage detection system. This system can help people to avoid the risk of gas leakage. With the increasing demand and consumption of LPG has made it necessary for you to monitor the level of LPG cylinders. So, you can get a little idea about when the gas cylinder will be empty and you can order another gas cylinder before the gas runs out. In today’s fast paced world people need to work smart. So, it is now possible to use IOT (Internet of Things), that’s why we have used mobile application to turn gas ON/OFF. Through this application we will get notification on our mobile when leak occurs and you will also get an alert through alarm system.
