Sonoff ZigBee LCD Temperature and Humidity Sensor SNZB-02WD

Sonoff SNZB-02WD ZigBee LCD Temperature and Humidity Sensor

The ZigBee SNZB-02WD is an advanced temperature and humidity sensor that provides precise real-time measurements, even in harsh outdoor conditions. With Zigbee 3.0 protocol and compatibility with Zigbee hubs, the device is ideal for smart home systems. The built-in 2.2-inch LCD display makes it easy to read data quickly, and the ability to change between °C and °F allows you to customize the temperature display to your preference.

Weatherproof and durable design
The SNZB-02WD can operate in a temperature range of -20°C to 60°C, and its measurement accuracy is ±0.2°C and ±2%RH, making it reliable even in cold stores, conservatories, or aquarium ecosystems. The IP65-certified housing protects the sensor from moisture and splashing, and UV resistance ensures long-term outdoor use, even in intense sunlight.

Smart integration and data analysis
With the eWeLink app, you can not only monitor conditions in your greenhouse, RV, or warehouse in real time, but also analyze data from the last 180 days (daily, monthly, or semi-annually). It's a great tool for optimizing crops or maintaining proper conditions for animals. Receive notifications of sudden temperature drops, such as a terrarium power outage, and react instantly.

Automation and voice control
The sensor allows you to create smart scenes, such as automatically activating the irrigation valve when the humidity drops below a set level. You can also check the temperature with a voice command—just ask your voice assistant a simple question, such as whether you’ll need a jacket before leaving the house. With integration with open-source platforms such as Home Assistant and the SONOFF ZBDongle series, you can easily fit the SNZB-02WD into your own home automation system.

Convenient installation and longevity for years to come
The sensor can be mounted in two ways—with a magnet or a hanging cord—depending on your needs and installation location. The CR2477 battery installed in the sensor lasts up to two years of operation, minimizing the need for frequent replacement.
