Automotive MiCS Air Quality Sensors (AQS)

Air Quality Sensors enable the climate control system of a car to measure pollution levels external to a vehicle. When the vehicle travels through a polluted area it triggers closure of the air inlet, moving the system into recirculation mode.

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.
