This alcohol sensor is suitable for detecting alcohol 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.

MQ 2:

This sensor monitor many kinds of gas, including: gas, butane, propane, methane, alcohol, hydrogen, smoke, etc. (It is a basic composition of range of MQ 3 and MQ5 )
