What is the function of the air quality sensor in Audi A1?

I have noticed that my Audi A1 has an air quality sensor. What exactly does this sensor do and how does it improve my driving experience?

The air quality sensor measures the level of pollutants and allergens in the air inside your vehicle.

Based on the readings from the sensor, the car's ventilation system can automatically adjust to maintain clean and fresh air inside the car.

This feature is especially useful for those with allergies or respiratory issues, as it helps to reduce exposure to harmful pollutants while driving.
