In-Depth: How MQ2 Gas/Smoke Sensor Works? & Interface it ...

In the presence of reducing gases, the surface density of adsorbed oxygen decreases as it reacts with the reducing gases. Electrons are then released into the tin dioxide, allowing current to flow freely through the sensor. Hardware Overview – MQ2 Gas Sensor Module . Since MQ2 Gas Sensor is not breadboard compatible, we do recommend this handy little breakout board. It’s very easy to use ...
