The MQ2 Gas Sensor Module is a high-sensitivity sensor used to detect flammable gases such as LPG, methane, propane, hydrogen, and smoke. It features both analog and digital outputs, allowing flexible integration with microcontrollers like Arduino, Raspberry Pi, ESP8266, and ESP32 for real-time monitoring and safety systems.
The sensor’s onboard potentiometer allows you to set a detection threshold for the digital output, while the analog output provides proportional gas concentration levels. Operating between 3.3V to 5V, the MQ2 module is ideal for gas leak detection systems, smoke alarms, air quality monitoring, and home automation solutions.
