Description:

This alcohol sensor is suitable for detecting alcohol concentration on your breathjust 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 simpleall 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.

Mikroelectron Code:

int sensorValue;
void setup()
{
  Serial.begin(9600); // sets the serial port to 9600
}
void loop()
{
  sensorValue = analogRead(0); // read analog input pin 0
  Serial.println(sensorValue, DEC); // prints the value read
  delay(100); // wait 100ms for next reading
}
