Description

HELLA’s rain/light/climate sensor features combined sensor control functions such as automatic windshield wipers, optimized lighting and air conditioning based on evaluation of solar loads and humidity in the vehicle, and also comes with a function to improve the visibility of the head-up display (HUD).

The rain/light/climate sensor module is one of the smallest sensors of its type on the market and features a flexible, modular design.

It combines five functions: rain, light, solar load, humidity and visibility of the head-up display.

These multiple functions can be combined as a package according to customer requirements.

The sensor’s modular design allows for up to 20 custom variants, such as:

  • Light sensor
  • Rain sensor
  • Rain/light sensor
  • Rain/light/sun load sensor
  • Rain/light/climate sensor (solar load and humidity)
  • Climate sensor (solar load and humidity)
  • Optional: Head-up display (HUD) with brightness control

The customer selects the variant that best matches his needs based on the individual requirements of each vehicle series.

The integration of a rain/light sensor considerably helps to improve visibility and comfort in a range of driving situations (e.g. in the rain, in tunnels and at night) and when exposed to diverse environmental influences (e.g. rain, sun, humidity).
