Abstract
An alcohol detection system incorporates a resistive touch sensor mountable in a vehicle for determining presence of alcohol based on changed skin resistance. An ignition interlock is provided in the vehicle and a microcontroller is connected to and receives data from the touch sensor and provides a signal to open the interlock to disable the vehicle upon receipt of data from the touch sensor exceeding a predetermined value. The system also employs operator identification and vehicle location systems with a data logger allowing the microcontroller to store data on test results, operator identification and vehicle location. Additionally, the system may employ a cellular communication system to allow reporting of the data to a remote location.
