Detects alcohol concentrations on your breath

Quantity

This alcohol sensor is suitable for detecting alcohol concentrations on your breath, just like your common breathalyzer. It has a high sensitivity and fast response time. Sensor provides an analog resistive output based on alcohol concentration. The drive circuit is very simple, all it needs is one resistor. A simple interface could be a 0-3.3V ADC.

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

Note: Easy connection to an ADC using this breakout board!
