Solar sensor

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.

The solar sensor consists of two photosensors. The photosensors work in the infrared range.

The solar sensor is used for the range of functions of the integrated automatic heating and air conditioning system (IHKA). The solar sensor measures the sunlight on the vehicle. When doing this, the sunlight on the driver's side and the passenger's sides are detected separately.
