The next generation air classification module (ACM) from ams is a highly sensitive and reliable device for detecting gases and odors carried into the cabin of a vehicle from outside.
The ACM uses MEMS gas sensor technology to accurately and reliably detect carbon monoxide (CO), nitrogen dioxide (NO2) and a broad range of volatile organic compounds (VOCs) which create unpleasant odors, such as manure or smoke. The ACM alerts the climate-control system to changes in the ambient atmosphere. The climate-control system can then prevent gases and odors from entering the cabin by closing the recirculation flap.
The ams ACM sets new standards for performance, integration and intelligence in automotive climate-control applications. It features LIN or PWM interfaces, is VDA compliant and is housed in a robust IP67-rated package which weighs less than 10 grams.
