Humidity Sensor

A special sensor system in conjunction with the control algorithms in the Climatronic reduces misting-up of the windows and enhances climatic comfort by managing the humidity levels inside the car.
From the data delivered by the humidity and temperature sensor in the base of the interior mirror, the Climatronic control unit calculates the dew point temperature of the air – that is, the temperature at which the air humidity would condense. An infrared sensor remotely measures the radiated heat on the windscreen, and calculates the window temperature. To prevent the windows from misting up, Climatronic regulates the volume of air projected on to the windscreen and, with the compressor switched on, also the air humidity inside the car.
Relative humidity based on interior temperature can also be kept at a pleasant level.
