MQ-3 Alcohol Sensor, Breakout Board + Arduino

lot has happened since our last article was published and to celebrate the continuance of bildr we’ll be playing with the MQ-3 Alcohol Gas Sensor. Coupled with the SparkFun Gas Sensor Breakout Board, connecting the MQ-3 to your Arduino is a breeze. The MQ-3 is a heater-driven alcohol sensor that outputs an analog signal (usually interpreted somewhere between 150 and 1023 depending on how long you let the se ...
