Zusammenfassung:	One or more inexpensive electrochemical gas sensors are paired with a selective ozone sensor. Ozone in ambient air influences the output signals of the electrochemical gas sensors. The unwanted ozone effects are removed from the output signals of the electrochemical gas sensors by comparing them with the selective ozone sensor output signals. The selective ozone sensor signals are removed from and/or added to output signals from the electrochemical gas sensors. True indications of concentrations of the sensed gases in the ambient air result from the compensation for ozone interference.
