VM72B-WiFi Air Quality Monitor
All-in-One CO₂, Temperature & Humidity Detection
Integrates real-time monitoring of CO₂ concentration, temperature, and humidity using a high-precision NDIR infrared sensor with auto-calibration for accurate long-term performance.
Smart Wireless Monitoring via TUYA App
Supports WiFi connection and data synchronization with the TUYA App, allowing you to remotely track CO₂ levels and environmental data on your smartphone anytime, anywhere.
Historical Data Logging & Temperature Offset
Built-in memory automatically records historical air quality data. Supports temperature offset adjustment to meet specific usage needs.
Visual & Audible CO₂ Alerts
Color LED indicators change with CO₂ concentration levels. When the value exceeds the set threshold, the device automatically triggers an alarm. The buzzer can be manually turned on/off as needed.
Auto Detection & Reliable Alerts
Continuously measures and detects air quality conditions. When exceeding set limits, the system initiates warnings to help you optimize ventilation and ensure a healthy indoor environment
