Gas sensor and a method for the detection of at least a sulfur-containing gas, ethanol or carbon monoxide

摘要

The invention relates to a method for detecting of at least a sulfur-containing gas, ethanol or carbon monoxide with the steps of: heating a sensitive layer on at least a first temperature (t1), wherein the at least a sulfur-containing gas, ethanol or carbon monoxide as a first target gas on the sensitive layer is adsorbed and / or in the sensitive layer is absorbed, measuring a first measured variable (m1) with respect to an electrical resistance of the the first temperature (t1), which is sensitive layer, and fixing of an item of information with regard to possible presence of the first target gas at least with a predetermined first minimum concentration and / or with respect to a concentration of the first target gas at least taking into account the first measured variable (m1), wherein a second measured variable (m2) for the a second temperature (t2) is not equal to the first temperature (t1) having a sensitive layer is measured and the information also taking into account the second measured variable (m2) is fixed. The invention also relates to a corresponding gas sensor.n="29"
