The MQ-2 Gas Sensor is a widely used sensor that detects the presence of flammable gases such as LPG, propane, methane, hydrogen, and smoke in the surrounding air. It features a sensitive SnO2 semiconductor sensing layer, which changes resistance with varying gas concentrations. The sensor provides both analog and digital outputs, making it compatible with Arduino, ESP32, Raspberry Pi, and other microcontrollers for real-time gas monitoring. With fast response and high sensitivity, the MQ-2 is ideal for building smoke detectors, gas leak alarms, and air quality monitoring systems.
