Principle Introduction:
The ZE29A-C2H5OH electrochemical alcohol sensor module is to detect exhaled alcohol gas. With electrochemical alcohol sensor as core part and built-in temperature compensation sensor, it has high accuracy, high sensitivity, and strong anti-interference ability. It’s integrated with pressure sensor, which can realize blowing action detection to further ensure the accuracy of measurement. This product is suitable for alcohol detection of drunk driving or before work.

Applications :
Portable alcohol detector;
Car alcohol testing
