A prototype of a mobile sensor system for breath control of respiratory air is introduced which can be connected via an adapter to a smartphone for on-line monitoring. This system runs an embedded metal oxide gas sensor in a thermo-cyclic mode and determines the alcohol content on the basis of the measurement results via an innovative calibration- and evaluation procedure ProSens3.0 in real time. The analysis results will then be displayed on the smartphone. Especially for alcohol control, the
