The automotive single-channel all-in-one air quality detection module is a multifunctional sensing unit designed for the automotive sector. It integrates sensors for particulate matter (dust), infrared CO₂, multi-gas AQS (CO, NO₂, NH₃), temperature and humidity, and VOCs. The module enables real-time monitoring of these parameters and communicates directly with the vehicle's HVAC system, providing the data necessary to optimize in-cabin air quality. Advanced intelligent algorithms ensure excellent responsiveness, stability, and high measurement accuracy.
