The MQ-2 Gas Sensor Module is a versatile gas detection module designed to detect the presence of smoke and combustible gases in the surrounding air. It is commonly used with Arduino, ESP32, Raspberry Pi, and other microcontroller platforms for gas monitoring and safety projects.
The MQ-2 sensor is sensitive to gases such as LPG, propane, methane, hydrogen, and smoke. The module provides both analog and digital outputs, making it suitable for applications where you need either gas concentration changes or a simple adjustable detection threshold.
