| Zusammenfassung: | A method and a device for measuring humidity may be suitable for determining the relative humidity in the high-humidity range. The device includes a sensor device, as well as a circuit connected to the same. The sensor device includes a capacitive humidity-sensor element, a temperature-sensor element, and a heating element, the humidity-sensor element being heated in at least one part of the humidity-measuring range. The ambient temperature is further ascertained by the circuit, from the heating power required in the heating mode, as well as from the measured, local sensor device temperature, in order to further determine the relative humidity. |
