AUTOMOTIVE PM2.5 MANAGEMENT APPLICATION

In-Cabin PM2.5 Management for Cleaner Cabin Air

Connect particulate sensing with intelligent air intake and filtration.

MAXMAC automotive PM2.5 and multi-in-one sensors provide the inputs for vehicle HVAC systems to compare air conditions, coordinate recirculation and monitor the cabin response.

APPLICATION BENEFITS

Make Cabin Particle Control More Responsive

Bring measured particulate conditions into decisions about incoming air, recirculation and cabin filtration.

Inside and Outside PM2.5 Awareness

Compare particulate readings from cabin and outside-air sensing points to inform vehicle air-management decisions.

Responsive Air-Intake Control

Give the HVAC controller particulate inputs for fresh-air and recirculation strategies as road conditions change.

Filtration Response Monitoring

Track cabin PM2.5 trends after airflow and filtration adjustments to support ongoing system evaluation.

Broader Cabin Air Context

Combine PM2.5 with available CO₂ and AQS inputs so particulate control also considers ventilation needs.

ROAD CONDITIONS & CABIN RESPONSE

Respond to Particle Changes Throughout the Journey

Outside-air conditions and cabin activity call for different responses. Inside and outside PM2.5 inputs help the vehicle controller decide when to adjust intake and when to prioritize cabin filtration.

Dusty roads and congested trafficUse outside particulate trends to inform air-intake decisions.

SENSING TO CONTROL

From Particle Sensing to Cabin Air Response

MAXMAC sensors provide particulate data. The vehicle controller and HVAC coordinate the response and use fresh readings to close the loop.
