Gas Leakage Detection and Solenoid Valve Control with Arduino

Introduction

Give your next Arduino project a nose for gases by including the MQ2 gas sensor module. This versatile sensor can detect LPG, smoke, alcohol, propane, hydrogen, methane, and carbon monoxide concentrations in the air. The MQ2 Gas Sensor Module is an excellent choice for building an indoor air quality monitoring system, a breathalyzer, or an early fire detection system.

Working Principle

The system operates on the principle of gas sensor technology, specifically using a gas sensor to detect the presence of potentially harmful gases in the environment. When the sensor detects a gas leak, it sends a signal to the Arduino microcontroller. The Arduino then processes this information and triggers a solenoid valve to shut off the gas supply.
