CO2 PM2.5 Multi-Function Air-Quality Detector Why you need this detector Know indoor air quality at a glance: monitors the pollutants and conditions that affect comfort and health so you can act when air becomes unsafe or uncomfortable. Prevent hidden risks: detects PM2.5, CO2, and gaseous contaminants (HCHO/TVOC) that standard CO2-only or particle-only meters miss. Maintain healthy indoor environments: use measurements to improve ventilation, reduce exposure to allergens and volatile chemicals, and track conditions that worsen respiratory symptoms. Key benefits Multi-parameter monitoring: one device measures particulate matter, gases, temperature, and humidity for a complete view of indoor air quality. Reliable particulate detection: PM2.5 sensor uses laser scattering technology for responsive and consistent particle readings. Gas and chemical sensing: HCHO / TVOC are measured with a semiconductor sensor to identify volatile organic compounds and formaldehyde; CO2 is measured independently to indicate ventilation needs. Environmental context: built-in temperature and humidity sensing helps interpret pollutant readings and informs comfort decisions. What it does (functions) Continuously measures PM2.5, CO2, HCHO, TVOC, temperature, and humidity. Provides actionable data so you can decide when to ventilate, run air purifiers, or change activities that produce pollutants. Helps identify trends over time so you can evaluate the effectiveness of mitigation strategies. Performance and compatibility PM2.5: laser scattering technology for accurate particle detection in indoor environments. HCHO / TVOC: semiconductor sensor for detecting volatile organic compounds and formaldehyde. CO2: dedicated CO2 sensor to assess ventilation and occupancy-related air quality. Temperature and humidity sensor for environmental context and more meaningful interpretation of pollutant levels. Designed for use in typical indoor spaces (homes, offices, classrooms, and similar environments) to support everyday air-quality decisions. Practical use scenarios Home with children or allergy sufferers: monitor PM2.5 and TVOCs after cooking, cleaning, or during pollen season to decide when to ventilate or run an air purifier. Office or meeting room: track CO2 levels to know when to increase fresh air supply and maintain alertness and comfort during long meetings. Nursery, classroom, or daycare: watch for elevated formaldehyde or TVOC levels from furnishings or art supplies and take steps to reduce exposure. What makes it stand out Consolidates multiple sensor types into one instrument so you don’t need separate devices for particles, gases, and environmental conditions. Uses proven sensing technologies (laser scattering for PM2.5; semiconductor for HCHO/TVOC; dedicated CO2 and temperature/humidity sensors) to give a fuller, more actionable picture of indoor air quality. Simple outcomes you can expect Quicker, data-driven decisions about ventilation and filtration. Better protection from airborne particulates and volatile chemicals. Improved comfort through monitoring of temperature and humidity alongside pollutant levels.
