What does AQS mean in a car?

[SanKing]

AQS stands for Air Quality Sensor in a car. This sensor can detect air turbidity, humidity, and toxicity. It can control the internal and external circulation of the air conditioning system. Here is more information about car air conditioning: 1. The car's air conditioning system should be cleaned at least once a year. Otherwise, many bacteria can grow inside the system, and the air blown out when the air conditioning is turned on may have an unpleasant odor. 2. The air conditioning filter should be replaced regularly. Otherwise, it can breed bacteria and cause unpleasant odors in the air conditioning. 3. If the air quality in your area is poor, replace the air conditioning filter with one that can filter PM2.5 particles. When driving at high speeds, it is not suitable to open windows for ventilation. In such cases, you can turn on the external circulation function of the air conditioning. When driving in urban areas, especially in congested or dusty areas, you should turn on the internal circulation of the air conditioning.
