Abstract
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
analysis demonstrates that the relative analysis error for the leading component ethanol was lower than 10% even in investigating ternary gas mixtures. Additionally, very promising results were obtained in first field tests.
