ABSTRACT:
An ethanol sensing unit and a method of using, wherein the unit is particularly suitable for use in a confined environment such as the passenger compartment of a passenger vehicle. The sensing unit comprises a device for collecting ethanol vapors while the device is at a first temperature, a device for heating the collecting device to a second temperature higher than the first temperature so as to release ethanol vapors from the collecting device, and a device for sensing the ethanol vapors released from the collecting device when heated by the heating device. The sensing unit is also adapted to delay the operation of the heating device until a period of time sufficient for the collecting device to adsorb ethanol vapors from air contained in the confined environment.
