In this project, we will make a smoke and gas leakage detector using Arduino. We have used the MQ2 Gas sensor module to detect Smoke and carbon monoxide concentrations present in Air. MQ2 is a versatile sensor that can detect LPG, smoke, alcohol, propane, hydrogen, methane, carbon monoxide, etc. This makes the MQ2 Gas Sensor Module an excellent choice for building an indoor air quality monitoring system, a breathalyzer, or an early fire detection system.

First, let’s see how this project works. The MQ2 sensor detects smoke and Carbon Monoxide values and sends them to Arduino. Arduino then processes these values and displays these values on the OLED display. It also checks if these values are above the safe level then it sends a command to the buzzer and a LED. Then the buzzer starts alarming with a flashing LED.
