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 CO? monitoring to detect particulate matter, odor pollution, and CO? 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 CO? 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 CO? 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.
