Abstract/Artist Statement

This project designs an accurate breathalyzer compatible with Android smartphones. The device is able to measure the user’s blood alcohol content, or BAC, by blowing a constant amount of breath. The user’s BAC is displayed on the supplied smartphone along with warnings for the legal limits in the user’s state. Breathalyzer must be calibrated to zero by the phone app. User can input the state or the phone can use GPS to identify local laws for driving under the influence. The phone app gives instructions regarding how to get an accurate reading as well as displays a BAC level with +/- 30% accuracy. The breathalyzer connects to an Android smartphone via bluetooth and is powered by a LiPo rechargeable battery. The device is compact enough to wield with the phone and store in a pocket.
