Smart temperature and humidity sensor SONOFF SNZB-02WD Zigbee

Product detailed description

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

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

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

Automation and voice control
The sensor allows you to create smart scenes, such as automatic activation of the irrigation valve when the humidity drops below a set level. You can also control the temperature by voice command - just ask the voice assistant a simple question, such as whether you need a jacket before leaving the house. Thanks to integration with open-source platforms such as Home Assistant and the SONOFF ZBDongle range, you can easily integrate the SNZB-02WD into your own home automation system.

Convenient installation and long service life for many years
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.
