Principle Introduction:
MIX1003B Semiconductor alcohol sensors for breathalyzer use.
Sensitive material of MIX1003B C2H5OH Semiconductor gas sensor is semiconductor material which is with lower conductivity in clean air. When the target alcohol gas exists, the sensor’s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit.
Feature:
* High sensitivity to wide range of alcohol
* High sensitivity to alcohol
* Long life and low cost
* High ant seismic
* Strong anti-interference ability
Application:
Personal usage alcohol meter breathalyzer
Commercial usage alcohol meter breathalyzer
Other usage Portable alcohol detectors
Alcohol gas alarm for motor vehicle drivers
