Claim Text:
1. An alcohol detection system comprising: a resistive vapor sensor having internal components of an alcohol vapor sensor element and a heating element, mountable in a vehicle for determining presence of alcohol based on ethanol content of vapor excreted from skin, said vapor sensor triggered for an initial reading by a touch sensor and triggered for a second reading at a predetermined time differential, one of the internal components, said alcohol vapor sensor element or said heating element, connected to automatically provide temperature compensation; an ignition interlock in the vehicle; a microcontroller connected to the internal component and providing feedback control to a heater in the resistive vapor sensor for temperature compensation and receiving data from the vapor sensor for comparison of the initial reading and the second reading, the microcontroller further connected to the ignition interlock and providing a signal to open the interlock to disable the vehicle upon a determination of differential of data from the vapor sensor at the initial reading and the second reading exceeding a predetermined value.
