Automotive Air Quality Monitoring Sensor AQM-1000

The automotive air quality monitoring sensor AQM-1000 is a MEMS (Microelectronic Mechanical Systems) sensor which based module for automatic HVAC air intake control. MEMS metal oxide semiconductor gas sensing elements for the detection of oxidizing and reducing environmental gases classify the intake air quality. According to the environmental gas concentrations and implemented internal air diagnostic validation, detailed classification levels (see look up tables below) are provided via LIN 2.0/LIN2.1 interface. In order to cover the detection of low gas concentration events as well as high gas concentration events, the sensitivity is automatically adapted by dynamically changing the lookup table.
