MQ2 Gas Sensor Module
Product Details
The MQ2 Gas Sensor Module is a reliable sensor designed to detect flammable gases and smoke in the air. It is commonly used in gas leakage detection systems, safety devices, and environmental monitoring applications. The sensor can detect gases such as LPG, propane, methane, hydrogen, alcohol, and smoke, making it useful for both industrial and DIY electronics projects.
The module works using a sensitive gas detection element whose resistance changes when exposed to combustible gases. This change is converted into analog and digital output signals, which can be easily read by microcontrollers like Arduino, Raspberry Pi, ESP8266, and ESP32.
The MQ2 module usually comes with an onboard comparator and adjustable potentiometer, allowing users to set the sensitivity level according to their application. Its simple interface and stable performance make it a popular choice for gas monitoring and safety projects.
