MQ-5 LPG, Methane & Propane Gas Sensor Module
The MQ-5 Gas Sensor Module is an affordable and reliable solution for detecting combustible gases like LPG, methane, propane, and natural gas. Whether you’re building a home safety system or working on an industrial monitoring project, this sensor offers dependable performance with easy integration into microcontroller-based setups.
Built using high-quality tin dioxide (SnOâ‚‚) sensing material, the module responds to the presence of combustible gases by changing its conductivity. This change is then converted into an electrical signal, allowing your system to monitor gas concentration in real time.
With both analog and digital outputs, the MQ-5 module gives you flexibility in how you read and process data. The onboard potentiometer lets you fine-tune sensitivity based on your application, ensuring accurate detection without false triggers from common environmental factors like smoke or alcohol vapors.
