Applications
In-Vehicle Air Purification / Intelligent Cockpit

In-Vehicle Air Purification / Intelligent Cockpit

Designed for in-vehicle air purification and intelligent cockpit applications, this module integrates dual PM, AQS, and CO₂ monitoring to detect particulate matter, odor pollution, and CO₂ concentration changes in real time. It supports intelligent linkage of HVAC recirculation/fresh-air switching and purification strategies to improve cabin comfort and safety.

Residential/Central Air Conditioning

Residential/Central Air Conditioning

Suitable for residential and central air conditioning systems, it combines dual PM, AQS, and CO₂ monitoring for comprehensive evaluation of particulate matter, odor gases, and air freshness, helping the system achieve more precise purification, fresh-air, and temperature control linkage.

Fresh Air System

Fresh Air System

Suitable for residential and commercial fresh-air systems, it uses coordinated dual PM, AQS, and CO₂ sensing to monitor indoor air quality changes and provide data support for fresh-air volume adjustment, filtration efficiency optimization, and air quality management, balancing comfort and energy efficiency.
