Microcontroller based Fire Extinguisher with Bluetooth Operated LPG Gas Leakage Detection and Prevention System

Abstract

Everything is getting automatic and smarter with the passing of days. It is time to make our homes smarter and automated. This system includes Arduino based fire extinguisher and Bluetooth based gas detection to make the daily life easier. Here we used two Arduino, one flame and gas sensor, three servo motors and one Bluetooth module. Gas sensor detects all type of gas and fire sensor detects flame spectrum. Bluetooth module is used to send message to consumer about the gas exceeded gas concentration and motors to serve our desired purposes like switch off the gas not, switch off the MCB and sprinkle water from fire extinguisher. With the help of all of these we made an automated system to detect any danger and to prevent it safely. The system detects the LPG leakage using a gas sensor and flames by a flame sensor. When the LPG concentration in the air exceeds the certain level, the Gas sensor detects the leakage and then it immediately alert the consumer by showing a message to specified mobile and turn off the gas regulator automatically. When fire catches inside a room, flame sensor detects it and automatically MCB will turn off and fire extinguisher automatically gets activated. In addition to this user can install IP webcam in their smart phones. It has unique IP address. Whenever he/she is outside from their places, they can easily monitor their places by just googling that unique IP address. For this purpose, user has to attach Arducam with the microcontroller.
