## Summary description

The Sonoff AirGuard TH SNZB-02DR2 is a ZigBee temperature and humidity sensor with an integrated LCD display for quick readings. Designed to monitor indoor climate, it reports temperature and relative humidity to compatible ZigBee hubs for automation and alerts. Suitable for home, office, greenhouse or storage use to track environmental conditions and trigger climate control or notifications.

## Long description

Sonoff AirGuard TH SNZB-02DR2 is a compact smart ZigBee temperature and humidity sensor with a large 3.6" high-contrast LCD that displays current temperature and humidity, 24-hour minimum and maximum values, and an air comfort indicator. The device uses a Sensirion SHT40 sensor for precise measurements, supports ZigBee 3.0 for integration with home automation hubs, and also offers Bluetooth Proximity mode for direct connection to a smartphone. Powered by two AAA batteries and housed in a PC+ABS enclosure, it is suitable for a variety of indoor environments.
Advantages
The AirGuard TH provides laboratory-grade accuracy (±0.2°C for temperature and ±2% RH for humidity) and continuous local readout on a 3.6" LCD so users can quickly check conditions without opening an app. ZigBee 3.0 connectivity enables low-power, reliable operation and easy integration with platforms like Sonoff, Home Assistant, Zigbee2MQTT, SmartThings, and voice assistants. Data logging, graphical history, and additional analyses (dew point, VPD, comfort index) allow informed decisions about ventilation, heating, and plant care. Proximity mode via Bluetooth allows basic use without a gateway.
Suitable for
Home rooms: bedroom, nursery, living room
Plant care: greenhouse or indoor plants
Food and storage areas: pantry, wine storage
Commercial or utility spaces: office, warehouse, basement

How to use
Install two AAA batteries and place the sensor in the desired location using the stand or wall-hang option. For integration with a ZigBee hub, put the sensor into pairing mode and add it to your ZigBee gateway; once connected you can view live readings, set alerts, and create automations via the compatible app or platform. If no ZigBee gateway is available, enable Proximity mode and connect directly to a smartphone over Bluetooth to read current values, calibrate, change units between °C and °F, or export logged data.
Usage recommendations
Place the sensor away from direct heat sources, airflow from vents, or areas of direct sunlight to ensure accurate readings. For reliable long-term monitoring, check battery level on the display and replace AAA cells before they are fully depleted. Use ZigBee integration for automated actions (humidifier, fan, or heater) and Proximity mode for occasional checks or initial setup.
