The gas-sensitive material used in the MQ316 odor sensor is a semiconductor material with low conductivity in clean air. When there is a gas to be measured in the environment where the sensor is located, the conductivity of the sensor increases as the concentration of the gas to be measured increases. Use a simple circuit to convert the change in conductivity into an output signal corresponding to the gas concentration .

Application

Widely used in breath odor detectors, portable alcohol detectors, etc.
