CO2 PM2.5 Multi-function Air quality detector What it does Measures key indoor air parameters so you can identify problems and take action: PM2.5 (fine particles) — sensor technology: laser scattering HCHO (formaldehyde) and TVOC — semiconductor sensor CO2 — CO2 sensor Temperature and humidity — temperature and humidity sensor Key benefits — why you need it Protect health: Detects PM2.5, formaldehyde, VOCs and high CO2 levels that can affect respiratory health, sleep and concentration. Make better decisions: Gives clear pollutant and environmental readings so you can ventilate, run an air purifier, or change behavior based on measured conditions. One device, complete view: Combines particulate, gas, CO2, temperature and humidity monitoring in a single instrument for a more accurate assessment of indoor air quality. Standout features Laser scattering PM2.5 sensor for sensitive particle detection. Semiconductor HCHO/TVOC sensor to detect volatile compounds and formaldehyde. Dedicated CO2 sensor to monitor ventilation and occupancy-related air quality. Integrated temperature and humidity sensing to put pollutant readings into environmental context. Practical attributes Function: Continuous multi-parameter air quality detection for indoor spaces. Compatibility: Suited for residential and commercial indoor environments where air quality matters. Size and material: Designed as a single, integrated detector; consult product specifications for exact dimensions and housing details. Performance: Uses established sensor technologies (laser scattering and semiconductor) to monitor particulate and gas-level indicators alongside CO2, temperature and humidity. Use scenarios Home / Nursery: Monitor PM2.5, formaldehyde and TVOCs after renovation or furniture delivery; verify safe conditions before a baby sleeps in the room. Office / Meeting Room: Track CO2 and VOC levels during long meetings to know when to ventilate and improve alertness and productivity. Kitchen / Workshop: Detect particulate spikes and VOCs from cooking, soldering or hobby work and take real-time steps to reduce exposure. How it helps you act Identifies which pollutant is elevated (particles vs gases vs CO2) so you apply the right remedy: ventilation, source removal, or filtration. Contextual temperature and humidity data help interpret pollutant readings and plan humidity control or HVAC adjustments.
