DM72B WiFi Version 10-In-1 Air Quality Monitor Support Tuya Smart App Control CO2, PM2.5, PM10, HCHO, TVOC Detector

1. This product is a multifunctional air quality monitor that combines various high-quality air sensors and a built-in fan to provide real-time monitoring of carbon dioxide (CO2), particulate matter (PM2.5/1.0/10), formaldehyde (HCHO), total volatile organic compounds (TVOC), temperature, and humidity. It not only captures various real-time air quality data but also supports smart WiFi, connecting via the Tuya app for easy operation. After connecting to your phone, you can view real-time data anytime, allowing you to understand the surrounding air quality conditions.
2. Smart linkage control: With the help of the Tuya smart platform, it can be linked with other smart home devices. For example, when the air quality monitor detects that indicators such as formaldehyde or PM2.5 exceed the standard, it can automatically trigger the air purifier to start purification mode, or link with the air conditioner to adjust indoor temperature and ventilation, creating a healthy and comfortable indoor environment for users.
3. Exceedance automatic alarm: Users can set alarm thresholds on the Tuya app. Once air quality data exceeds the set safety range, the app will immediately push notifications to remind users to take corresponding measures, such as opening windows for ventilation, to promptly ensure the health and safety of family members.
4. Data visualization and historical traceability: The app presents air quality data in intuitive chart forms, supporting querying change curves for three different time dimensions: daily, monthly, and yearly, making it convenient for users to understand air quality trends. At the same time, historical data storage is traceable, providing data support for a healthy environment.
5. Multi-device management: Users can manage multiple air quality monitors in one app, comprehensively understanding the air quality conditions in various rooms at home.
6. Built-in rechargeable lithium battery, supports charging via Type-C interface.
