Product Description
The MQ‑2 Gas Sensor is a versatile and affordable sensor module designed to detect smoke, LPG, methane, hydrogen, and other combustible gases. Built with a sensitive SnO₂ (tin dioxide) layer, the sensor changes resistance when exposed to target gases, making it ideal for gas leakage detection systems, fire alarms, and IoT safety devices. With a fast response time, high sensitivity, and simple analog/digital output, the MQ‑2 is widely used in Arduino, Raspberry Pi, and microcontroller projects for both hobby and professional applications.
