Principle Introduction
| The sensing material of MEWOI-MIX1013 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. |
Features
| * High sensitivity to wide range of alcohol * High sensitivity to alcohol * Long life and low cost * High ant seismic |
Application
| * Personal usage alcohol meter breathalyzer * Commercial usage alcohol meter breathalyzer * Other usage alcohol detectors |
