Product Description
The MQ‑5 Gas Sensor is a versatile and affordable sensor module designed to detect LPG, natural gas, 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 alarms, fire detection systems, and IoT safety devices. With high sensitivity, fast response time, and simple analog/digital outputs, the MQ‑5 is widely used in Arduino, Raspberry Pi, and microcontroller projects for both hobby and professional applications. Its compact design ensures easy integration into embedded systems and portable devices.
