IoT-based LPG Gas Leakage Detection and Prevention System

LPG (Liquefied petroleum gas) is a form of natural gas which has been liquefied under extreme pressure and then contained in a metal cylinder. It is very sensitive to fire and can cause a great disaster if it's exposed to any fire source without precaution. LPG is more available than any other natural gas so most people choose LPG for their needs like cooking and other needs. So the event of gas leakage or blast occurring by leaked gas is frequently seen and heard. In this paper, a device has been introduced to prevent any possible accident from happening. It is called Smart Gas and Fire detector. The device can detect any spillage of gas and fire very quickly and send a response via gsm tool directly to the user very fast and a buzzer is set up to alert. The device also has another feature with an exhaust fan which will be activated in case of gas leakage and fire detected, to reduce the density of gas by pushing the air outside. The device is designed to detect gas and fire as quickly as possible. Its performance is the same in case of closed and open both types of room.
