The Breathalyzer System will be integrated into sub systems, the control box unit and the hand held unit. For the control unit, this device will determine if the car is on, how fast the car is going and other characteristics of the car itself. This will require a logic unit that will be able to read data, store, and write it to a memory device.

The handle held unit will be used to display the data and have a fuel cell sensor that will read input from the user. In order to synchronizing the systems together, a microcontroller will be used to communicate the data wirelessly.

The process of flow of this Breathalyzer System will start by having a control box and the handle held unit. The control box requires validation from the hand held unit. Once the user takes a sample to the hand held unit the user will hit a push button that will initiate data to start to be sampled. The data will be read will be blood alcohol concentration.
