MQ-5 Gas Sensor Module H2 LPG CH4 CO Alcohol

The MQ-5 Gas Sensor Module is a reliable and affordable sensing solution designed for detecting a wide range of flammable and hazardous gases. Compatible with hydrogen (H2), LPG, methane (CH4), carbon monoxide (CO), and alcohol vapours, this module is ideal for use in gas leakage detection systems, safety alarms, and environmental monitoring applications.

Built around the MQ-5 sensing element, the module operates on a simple analogue and digital dual output system, making it highly compatible with Arduino, Raspberry Pi, ESP32, and other popular microcontroller platforms. The onboard potentiometer allows easy sensitivity adjustment to suit your specific detection requirements.

With its fast response time, stable performance, and wide detection range, the MQ-5 is a go-to choice for hobbyists, students, and engineers building smart home safety systems, industrial gas monitors, or IoT-based alert devices. The compact PCB design ensures easy integration into any project breadboard or custom enclosure.

A must-have sensor module for any electronics safety project.
