AQS (Air Quality Sensor) serves multiple crucial functions in automobiles, providing occupants with a healthier and more comfortable driving environment. By monitoring the quality of air inside the vehicle, AQS ensures not only the efficient operation of the air conditioning system but also prevents harmful substances from entering the cabin.

Firstly,
AQS, as a key technology, is applied in the automatic air conditioning systems of high-end vehicle models. By monitoring the air's turbidity within the vehicle, AQS can accurately determine whether adjustments to the air conditioning circulation mode are necessary.
When the vehicle is stuck in city traffic, AQS senses external exhaust emissions and airborne particles, providing timely feedback to the processor. This enables the automatic air conditioning system to intelligently switch to the recirculation mode based on the analysis results, preventing toxic gases from entering the cabin and safeguarding the health of occupants.

Secondly,
the activation of the AQS sensor plays a decisive role in the normal operation of the air conditioning system. If the AQS function is not turned on, the automatic air conditioning system cannot obtain information about the air's turbidity within the vehicle, limiting its ability to make corresponding adjustments.
With the AQS button activated, the air conditioning system can accurately perceive changes in the air quality inside the vehicle and adjust accordingly based on this data. Enabling this function not only prevents the generation of unpleasant odors from vehicle exhaust in the cabin but also provides a better breathing environment, ensuring a more comfortable journey for occupants.

Additionally,
AQS can intelligently adjust the air conditioning circulation mode based on different road conditions. When driving on highways, where opening windows for ventilation may be challenging, AQS allows occupants to easily switch to the outside circulation mode, allowing fresh external air to flow into the cabin, maintaining a comfortable temperature and humidity.
Conversely, when driving through areas with a high level of dust, the AQS sensor prompts the driver to activate the vehicle's internal circulation function, preventing harmful particles from entering the cabin and effectively protecting the health of occupants.
