[Comprehensive Air Quality Monitoring] The Smart Air Box is a cutting-edge device designed for remote air quality monitoring in your home. It simultaneously detects five essential environmental parameters: formaldehyde, VOCs, CO2, temperature, and humidity, ensuring a comprehensive understanding of your indoor air quality [Automatic Environment Optimization] When environmental parameters exceed safe levels, the Smart Air Box intelligently connects to Tuya Smart Home devices, such as air conditioners, fresh air systems, humidifiers, and air purifiers. This automatic optimization ensures that your home environment remains safe and comfortable at all times [Seamless Device Integration] Through the Tuya app's automation features, the Smart Air Box can link with various devices in your room. For instance, if elevated levels of formaldehyde or VOCs are detected, your smart air purifier will automatically activate. If CO2 levels rise too high, the smart fan will turn on, and temperature anomalies will prompt the air conditioner to adjust accordingly [User-Friendly Notifications] The Smart Air Box not only monitors air quality but also keeps you informed. When any parameter exceeds its safe threshold, you will receive instant SMS alerts, ensuring you stay aware of your indoor air conditions (smart linkage features require device pairing for full functionality) [Smart Home Compatibility] Designed for modern smart homes, the Smart Air Box enhances your living environment by seamlessly integrating with your existing Tuya-enabled devices.
