Sensor arrangement for use in motor vehicle inner space, has dew point sensor for determining temperature of windscreen of motor vehicle, and ventilation device for pressurizing dew point sensor with air from motor vehicle inner space

摘要

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.
