About MQ2 Gas Sensor

The MQ-2 Gas Sensor is a widely used semiconductor sensor designed for detecting combustible gases and smoke. It operates on the principle of changing resistance with gas concentration. This sensor is highly sensitive to LPG, propane, hydrogen, and smoke, making it perfect for gas leakage detectors, fire alarms, and air quality monitoring systems. It features a simple drive circuit, fast response time, and long life. The module typically includes an analog output for precise measurement and a digital output with an adjustable potentiometer for threshold-based alerts. Its low cost and compatibility with popular platforms like Arduino and Raspberry Pi make it an excellent choice for hobbyists, students, and professionals building DIY electronics projects.
