Principle Introduction:
The sensing material of 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 alcohol gas concentration.
Feature:
High sensitivity to wide range of alcohol
High sensitivity to alcohol
Long life and low cost
High anti-seismic
Application:
Personal usage alcohol meter breathalyzer
Commercial usage alcohol meter breathalyzer
Other usage alcohol detectors
