  • Large 3.6" LCD display: Easy-to-read high-contrast data display with 24-hour indicators and a graphical comfort indicator.
  • Sensirion SHT40 sensor: Professional laboratory-level accuracy with minimal deviation of $\pm\text{0.2°C}$ and $\pm\text{2% RH}$.
  • ZigBee 3.0 & Bluetooth connectivity: Dual wireless communication capability for maximum energy efficiency and fast response time.
  • Hub-free operation: Direct connection to your smartphone via Proximity Mode (Bluetooth) for monitoring and data export.

Absolute control of the microclimate at a glance

Do you want to ensure the ideal conditions for your sleep or the protection of your plants? The Sonoff AirGuard TH SNZB-02DR2 set gives you all the information you need on an impressive 3.6-inch display. Without opening any app, you can instantly see the current values, the minimum and maximum of the last 24 hours, as well as the smart air comfort indicator.

Smart automations and advanced analytics

Create the ideal environment by connecting the sensor to your smart ecosystem. You can program the humidifier to turn on automatically when the air becomes dry or the ventilation when humidity levels rise. Through the app, you have access to detailed charts, 6 months of history, as well as specialized measurements such as the dew point and the VPD index.

Flexible connection and mounting that stands out

Even if you don’t have a central ZigBee hub, Bluetooth Proximity Mode lets you manage the sensor, calibrate it, and export data directly to your phone. With a compact design made of durable PC+ABS material and powered by two standard AAA batteries, you can place it upright or hang it in any room, basement, or greenhouse.
