It basically detects alcohol concentration within the breath. It’s very similar to the breath analyser. Some characteristics include: Response time is FAST (we all want that) in addition to that, it’s very sensitive which means it works well.

The analog resistive output it provides is the result from the alcohol concentration that gets detected, Note that only one resistor is needed! It has a very simple interface such as 0-3.3V ADC. And last but not least, the drive circuit is very user-friendly and easy to use.

Now available in Dubai, UAE, Oman, and Qatar.

Please review the datasheet for conversions to ppm then for BAC.
