Principle Introduction

The sensing material of Xtester-MIX1003 Alcohol Sensor is tin dioxide SnO2, which has low conductivity in clean air. When the alcohol gas exists, the conductivity of the sensor will be raise according to the gas concentration goes up. Through a simple circuit, to convert the changes of conductivity to correspond to the gas concentration.
