Product Features:
Prevent Office Fatigue
Prioritizes indoor CO2 concentration monitoring; sends a reminder for timely ventilation when CO2 exceeds 1000ppm—a level that impairs work efficiency and physical health.
Ambient Noise Monitoring
Built-in sound level meter provides real-time feedback on decibel values (dBA) of the office environment, helping you create a quiet and focused workplace.
CO Carbon Monoxide Early Warning
Offers full-range 0-999PPM CO monitoring for potential risks in enclosed air-conditioned rooms, safeguarding respiratory safety at all times.
Stable DC 12V Power Supply
Adopts DC 12V/2A direct current power supply, far more stable than battery power and ideal for 24/7 non-stop continuous monitoring.
Smart Scene Customization
Works with the scene function of Smart Life App; customizable to set up triggers like "auto-push notifications to mobile phones when CO2 levels are excessively high".
Wide Temp & Humidity Monitoring Range
Adapts to a working temperature of 0-50℃ and humidity of 0-95%, meeting the monitoring needs of various offices and laboratories.
Historical Data Tracking
Check air quality trends via the App to evaluate the efficiency of office ventilation and the effects of environmental improvement measures.
Flexible Installation
Features a compact design (1120g including packaging), suitable for placement on office desks, in meeting rooms or wall-mount installation.
