Structure
The rain and light detector sensor is comprised of a combination of light-sensitive sensor elements and an LED.
All components are mounted on a printed circuit board in the sensor housing.
An optical element rounds off the sensor housing towards the windscreen. The optical element's task is to bundle
and align the outgoing and incoming light. The entire sensor is secured to the windscreen using an adhesive film.
The sensed area measures 300mm

.
The LED and a photo diode are used for rain detection, whilst an ambient light and a remote
sensor are used for light detection.
The priority of both rain and light detection is subordinate to manual actuation of the relevant switch
elements. This means that even if these assistance functions malfunction, manual activation of the wipers
and driving lights always takes precedence.
