SparkFun Alcohol Gas Sensor - MQ-3 Biometrics Surveillance Cameras This device is also suitableThis alcohol sensor is suitable for detecting alcohol concentration 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. Features: 5V DC or AC
