Automotive MiCS Air Quality Sensors

Air Quality Sensing (AQS) modules

AQS principle

By measuring pollution levels external to a vehicle with an Air Quality Sensor, the climate control system of a car is able to close the air inlet (recirculation mode), when the vehicle travels through a polluted area.

The following manufacturers trust SGX Sensortech's sensors to protect their customers:

• BMW : X3
• Citroën : C4 Picasso
• Ford : Mondeo
• Mercedes : A-class, B-class
• Renault : Laguna, Espace, Vel Satis
• Volvo : S40, V50

SGX Sensortech offers a wide variety of AQS solutions, each of which integrates two dedicated gas sensing chips, one for reducing gases (CO/HC) and one for oxidizing gases (NOx). These modules measure a broad range of reducing gases that are commonly found in traffic pollution, including CO, hydrocarbons and NOx.
