ABSTRACT:
An apparatus for monitoring the alcohol content of an individual, preferably in connection with vehicle operation, has a sensor head coupled to a remote control module. The sensor head measures both breath pressure and breath alcohol levels. The data from the sensor head is processed by the control module to determine whether a valid breath sample exists and what action is to be taken based upon the alcohol level of the breath.
