Air quality sensor

Air quality sensor

Air quality sensors detect pollutants such as carbon monoxide or unburnt hydrocarbons and forward information to the control unit of the vehicle air conditioning system for further processing. The vehicle air conditioning system can use the data from the air quality sensor to independently and optimally control various parameters, such as interior temperature, the position of the recirculation flap, or the fan speed.
