Alcohol breath tester with Arduino
posted December 19 2010 15:25.53 by Giorgos Lazaridis

Daniel Andrade probably got some tickets for drinking and driving, so he decided to make a breath analyzer to check for alcohol. The basic component of this project is the alcohol gas sensor MQ-3. An Arduino acquires data from this sensor and analyzes them. There are 10 LEDs that will light according to the alcohol percentage that the sensor got. Read his page for more info.
