Zigbee IP65 Temperature and Humidity Sensor

The SNZB-02WD is a Zigbee LCD smart temperature and humidity sensor with a unique design. The core sensor is protected by an IP65-rated housing and measures temperature and humidity through an internal waterproof and breathable membrane, ensuring reliable performance even in humid or misty environments. This makes the device ideal for monitoring outdoor conditions on windows, in gardens, or similar areas.

The SNZB-02WD features a 2.2-inch LCD display that clearly shows temperature and humidity. It is UV-resistant, ensuring durability even under direct sunlight. The sensor reliably measures temperatures even in cold environments. With an accuracy of ±0.2°C for temperature and ±2% relative humidity, it provides near-instant and reliable data.

The SNZB-02WD is compatible with Zigbee hubs supporting the Zigbee 3.0 protocol, including devices like SONOFF iHost, NSPanel Pro, ZBBridge-P, ZBBridge-U, ZBDongle-E, ZBDongle-P, Echo 4th Generation, Echo Show 2nd Generation, and Echo Plus 2nd Generation. *Note: Amazon Hub does not support humidity monitoring. It also integrates seamlessly with open-source platforms like Home Assistant—via SONOFF ZBDongle-P/E, Home Assistant SkyConnect, Connect ZBT-1, or the Zigbee multi-adapter from SMLIGHT (SLZB series)—offering a fully customizable and local temperature management solution without cloud dependency.

With the eWeLink app, you can access temperature and humidity data by day, month, or half-year. It provides storage for up to 180 days. Historical data can be viewed and exported, helping you better understand your garden and optimize plant care. The eWeLink app also allows you to create smart scenes that send notifications for deviations or set up automations based on temperature or humidity changes. For example, you can instantly receive a notification on your phone if a power outage causes the temperature in your terrarium to drop suddenly. Or, if the air becomes too dry, the water valve for irrigation will automatically activate to maintain optimal humidity in your garden.

2.2″ LCD Screen Display Easily monitor temperature and humidity on the clear LCD screen.

Unique Waterproof Structure Design SNZB-02WD is housed in an IP65-rated casing, featuring an internal waterproof, breathable membrane, ensuring reliable performance even in humid or misty environments.

±0.2℃/±2%RH Accurate Measurement With ±0.2℃ accuracy for temperature and ±2% RH for humidity, you can trust the stability and accuracy of real-time readings.

IP65 Waterproof Rating Ensures stable performance even in humid, splash-prone environments.

Zigbee 3.0 Compatible Supports Zigbee hubs using the Zigbee 3.0 protocol, like SONOFF iHost, NSPanel Pro, ZBBridge-P, ZBBridge-U, ZBDongle-E, ZBDongle-P.

Not compatible with Philips HUE Bridge, as Philips uses a proprietary Zigbee protocol that does not allow third-party devices.
