Description: This 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 circuit Requires heater voltage Operation Temperature: -10 to 70 degrees C Heater consumption: less than 750mW Dimensions: 16.8mm diameter 9.3 mm height without the pins Documents: Datasheet Arduino Tutorial in Portuguese Wiring Example Arduino Breathalyzer Another Breathalyzer bildr Tutorial
