1.8-in-1 indoor air quality meter — multi-parameter monitor with NDIR CO2 sensor and WiFi connectivity Why you need it See and act on real indoor air risks: monitors carbon dioxide (CO2), particulate matter (PM1.0, PM5, PM10), formaldehyde (HCHO), total volatile organic compounds (TVOC), temperature and humidity so you can improve ventilation, reduce irritation and protect sensitive occupants. Remote, real-time awareness: WiFi connectivity and the Life app deliver instant readings and historical data to your phone for easy tracking and analysis. Clear alerts that prompt action: color-coded levels and an audible alarm notify you when air quality worsens so you can ventilate or take corrective steps immediately. Key benefits and standout features Accurate CO2 measurement: built-in NDIR sensor provides reliable carbon dioxide readings to help you control ventilation and indoor comfort. Comprehensive air profiling: single device reports CO2, PM1.0/PM5/PM10, HCHO, TVOC, temperature and humidity for a complete picture of indoor air quality. At-a-glance display plus remote control: LCD screen shows live readings; you can also turn the screen off from the Life app when needed. WiFi + Life app compatibility: transfer data to your mobile device for remote monitoring, history review and simple setup. Color-coded visual alarm and audible alert: green (safe), orange (bad) and red (unhealthy); an alarm sounds when concentrations exceed the set alarm value (orange) so occupants can respond quickly. Rechargeable Type-C power: charges via Type-C cable. After a full charge the unit can run continuously for up to 2 hours; for uninterrupted monitoring, keep the device connected to a power supply during daily use. What it measures Carbon dioxide (CO2) — NDIR sensor Particulate matter — PM1.0, PM5, PM10 Formaldehyde (HCHO) Total volatile organic compounds (TVOC) Temperature and humidity Practical applications Bedrooms and nurseries: monitor CO2 and humidity overnight; use the Life app to review trends and turn off the LCD screen to avoid light disturbance. Home office and shared meeting rooms: track CO2 and PM levels to know when to open windows or run ventilation for better concentration and fewer symptoms. Renovation and cleaning periods: detect HCHO and TVOC spikes and monitor particulate levels when painting, installing new materials or doing dusty work. Usage and performance notes Connect the meter to your WiFi network and the Life app to receive real-time data and historical logs. Audible alarm activates when gas concentrations exceed the set alarm threshold (orange); visual status uses green/orange/red to indicate safe, poor and unhealthy levels. Powered via Type-C charging cable; fully charged operation lasts up to 2 hours. For continuous monitoring, keep the unit plugged into power during regular use. What’s included or required Device with LCD screen and built-in sensors Type-C charging cable (for charging and continuous power) Life app (mobile device required for app control and WiFi data transfer) This air quality meter combines NDIR CO2 sensing, multi-pollutant detection and WiFi app control to give clear, actionable indoor air data and timely alerts so you can maintain a healthier indoor environment.
