What is the purpose of the Audi 80's external temperature sensor?

I noticed a temperature sensor on the front of my Audi 80 and I'm curious to know what it's used for and how it works.

The external temperature sensor on the Audi 80 is used to measure the external temperature and send this information to the car's climate control system. It helps to regulate the temperature inside the car for optimal comfort and function. In addition, it is also used to display the outside temperature on the car's dashboard.

The Audi 80's external temperature sensor is also an important safety feature. It helps to detect icy or freezing conditions outside and alert the driver through the car's warning system. This allows the driver to adjust their driving behavior and be more cautious in potentially hazardous weather.

In some models, the external temperature sensor is also used for the car's automatic headlights. It can detect changes in ambient light and trigger the headlights to turn on or off accordingly. This adds an extra level of convenience and safety for the driver.
