II. Working principle
TVOC: Direct detection of various volatile organic gases (formaldehyde, benzene, alcohol, etc.), reflecting the comprehensive pollution level.
eCO₂: Non-direct measurement of CO₂, but converting VOC response into equivalent carbon dioxide concentration for risk control.
MEMS micro-heating: Maintains a working temperature of approximately 300°C to ensure stability and anti-interference.
III. Main applications (core scenarios)
Location: Low-cost, digital, universal indoor air quality monitoring
Smart home / household appliances
Home / vehicle air quality detector
Air purifiers, new fans, air conditioners: control (automatically turn on when)
Smart speakers, panels: Embedded IAQ monitoring
