Sensata's patented Solar Twilight Sensor uses a combination of our Solar and Twilight technologies. This combination offers OEMs the benefits of two functions in one package;
saving space and eliminating instrument panel clutter. Using the solar signal, the climate control system can automatically adjust the temperature setting to maintain occupant comfort regardless of temperature changes caused by solar loading variations. Our patented diffuser technology provides horizon-to-horizon sensor response that allows the sensor to measure the solar heating, independent of the sun's elevation. This technique provides an accurate response model for the sensor to compensate for vehicle roofline position and glass.
The Twilight function works with lighting control to improve driver safety by making the vehicle more visible to other vehicles and pedestrians. Custom photo ASICs and proprietary optical plastics allow the sensor to respond to light like the human eye. The sensor generates an output directly proportional to the ambient light level.
