Abstract

The disclosure relates to an operating method for a gas sensor, in particular a gas sensor for detecting asthma. According to said method, nitrogen monoxide or nitrogen dioxide is detected in a measuring phase and the gas sensor is heated by a heating device in a desorption phase in order to accelerate desorption. The heating process is continued until the temporal alteration of the measuring signal of the gas sensor falls below a threshold value.
