Principle Introduction

The gas sensing material used in the Xtester-MIX3003 gas sensor is a semiconductor material with low conductivity in clean air. When there is alcohol vapor in the environment where the sensor is located, the conductivity of the sensor increases with the increase of the alcohol gas concentration in the air. The change in conductivity can be converted into an output signal corresponding to the gas concentration using a simple circuit.
