The sensor arrangement (10) comprises a dew point sensor (16) for determining the temperature of windscreen (12) of motor vehicle, and a ventilation device (18) for pressurizing the dew point sensor with air from the motor vehicle inner space. The dew point sensor comprises a temperature sensor for the acquisition of internal room temperature of motor vehicle. The temperature sensor cooperates with a sensing element for the acquisition of air humidity in motor vehicle inner space. Die Erfindung betrifft eine Sensoranordnung (10) mit wenigstens einem Taupunktsensor (16) zum Bestimmen eines Klimaparameters in einem Kraftwageninnenraum, insbesondere einer Luftfeuchtigkeit, wobei eine Belüftungsvorrichtung (18) zum Beaufschlagen des wenigstens einen Taupunktsensors (16) mit Luft aus dem Kraftwageninnenraum vorgesehen ist.
