>> GROVE ALCOHOL SENSOR FOR ARDUINO MICRO CONTROLLERS
Occassionally you stumble across some cool accessories for arduino - here is
Grove Alcohol Sensor
is a complete alcohol sensor module for arduino devices - that provides good
sensitivity measuring the amount of alcohol in the air. With a small amount of
additional hardware it is possible to build a fully functional breathalyzer.
In fact, someone already has - it is called the
which integrates the sensor into an small tin box using an
IOIOMint board for android coupled with an
android application with a myriad of features that will keep you honest
and safe while you are out on the town.
While the IOIOMint isn't an arduino device - I was able to hook one of the
sensors up to a spare arduino UNO I had lying around and ran the sensor
though its paces. It typically reports a value between 500 and 900, and a
value over 650 indicates that there is alcohol present in the vicinity of
In the office we tested how quickly we could push its limits during a
hack night with beers.
