Abstract
A signal (Snormal) is provided to a heat element of a temperature sensor, which is recorded as a step response (Lruh, Lbew). From the difference of the step response compared with the reaction adaptively determined with the temperature sensor at zero air circulation, air flow or no air flow is determined.
