Product Features:
Allergy-Focused Detection
Features a dedicated pollen monitoring function with a measuring range of 0-500µg/m³, helping allergic individuals take timely protective measures.
Ultra-Fine PM1.0 Particle Monitoring
Detects 1.0-micron ultra-fine particles (e.g., bacteria, dust) smaller than PM2.5, providing an enhanced level of health protection.
Harmful TVOC Gas Analysis
Enables real-time tracking of volatile organic compound (TVOC) concentrations including formaldehyde, preventing long-term harm to family health from decorative pollution.
Audible & Visual Alarm Alerts
Triggers an immediate alarm when contaminants (e.g., CO2, PM2.5) exceed the preset limits, shielding children from the risks of these "invisible killers".
3-Minute Quick Calibration
Supports manual calibration function; sensor accuracy can be restored in just 3 minutes, ensuring the stability of long-term monitoring data.
At-a-Glance Comfort Level
Displays temperature and humidity in real time, helping you maintain the optimal indoor environment for human comfort (21-27℃ and 40%-60% humidity).
Smart Linked Purification
Connects with air purifiers via the App or relay interface, which automatically activates the purification mode when air quality deteriorates.
Ultra-Simple Setup Logic
Wi-Fi reset, unit conversion (℃/℉) and factory reset can all be completed with just a few buttons, making it extremely user-friendly for household users.
