The SONOFF AirGuard SNZB-02M is a smart indoor environmental sensor that monitors temperature, humidity, and atmospheric pressure. In addition to primary readings, it calculates dew point and vapor pressure deficit (VPD) to deliver a comprehensive overview of your indoor climate via Zigbee 3.0.
Accurate monitoring and custom notifications
With measurement precision of ±0.2°C for temperature, ±2% RH for humidity, and ±0.1 hPa for air pressure, the sensor detects subtle environmental changes. Set targeted thresholds in the mobile application to receive alerts when values exceed comfortable levels.
Smart automations via Zigbee 3.0
Connecting to a Zigbee hub enables seamless integration into automated routines. Based on real-time readings, the sensor can trigger actions on other smart devices, such as turning on humidifiers, fans, heaters, or air conditioners.
Long battery life and versatile installation
Powered by a single CR2477 battery, the device offers over 2 years of autonomous operation. Measuring 45 × 45 × 17.6 mm and weighing 27.3 g, it can be mounted using the included metal plate, 3M double-sided tape, or mounting screw.
