Abstract/Artist Statement
The project consists of a Blood Alcohol Content smartphone application using a hardware breathalyzer device. The breathalyzer device consists of a semiconductor based alcohol sensor, a bluetooth module, a toggle switch, a 9V battery pack, and a 3D printed case. The user will blow into the breathalyzer for a predetermined amount of time ample enough to gather data on the user’s BAC. This will pass through an Arduino Uno that will convert the breath of the user into analyzable data that can be passed through an API to our application over Bluetooth. The smartphone app reports the user’s BAC to them, along with helpful statistics such as the amount of time until they will be fully sober. Should they test above the legal limit, it will also display the amount of time until their BAC is below 0.08 and give them the option to call a predetermined emergency contact directly from the app. There is also a feature allowing the user to input the number and type of drinks they have had to get an estimate of their BAC based on their gender, weight, and time since the start of consumption in the event that the breathalyzer device is unavailable.
