· How does the MQ2 sensor work? When this sensor is powered on, the tin dioxide heats up to a high temperature. At that point, oxygen is absorbed to the surface. Then, when the gas we are measuring is brought close to this sensor, it reacts with the tin dioxide to reduce the surface absorption of oxygen. After, the electrons are released into the tin dioxide. Then the current flows freely. In this …
