Abstract: The cellular telephone/breath analyzer combination increases the functionality of the cellular telephone by informing the user of his/her breath alcohol concentration. The visual display of the cellular telephone displays the breath analysis function. Using the keypad of the cellular telephone, the user can instruct the cellular telephone/breath analyzer to perform a breath analysis. When the user exhales into the breath analyzer, a microcontroller and digital processor disposed within the cellular telephone convert the ethanol gas sensor reading into a breath alcohol concentration indicator on the visual display of the cellular telephone.
