Description :
The MQ-5 Gas Sensor Module is a cost-effective and reliable solution for detecting a wide range of combustible gases, including LPG, Hydrogen (H₂), Methane (CH₄), Carbon Monoxide (CO), Propane, and Natural Gas. It is widely used in both home and industrial gas leakage detection systems due to its high sensitivity and stable performance.
This module is designed for easy integration with microcontrollers such as Arduino, Raspberry Pi, and other IoT platforms. It provides both analog and digital outputs, allowing users to monitor gas concentration levels as well as trigger alerts when gas levels exceed a predefined threshold. The onboard potentiometer enables precise adjustment of sensitivity based on application requirements.
The MQ-5 sensor operates using tin dioxide (SnO₂) as the sensing material. In clean air, the sensor exhibits low conductivity, but when combustible gases are present, the conductivity increases proportionally with gas concentration. This change is converted into an output signal for easy detection and processing.
