Zigbee 3.0 Smart Temperature Sensor with LCD Display and Probe | Sonoff SNZB-02LD
The SONOFF SNZB-02LD is a Zigbee 3.0 smart thermometer with an LCD screen, an IP65 body and a 1.5 m temperature probe. The probe measures from -40°C to 115°C, so it can read the temperature of liquids or closed spaces such as fridges, freezers, water tanks and aquariums, while the screen stays where you can see it.
Key Features
1.5 m probe, -40°C to 115°C: The long external probe reaches places a normal room sensor cannot, such as inside a fridge, a freezer or a water tank. It covers a wide range from -40°C to 115°C.

LCD display: The current temperature is always visible on the LCD, so you can check it at a glance without opening the app.
IP65 protection: The thermometer is rated IP65 for humid and splash-prone places. It is not meant to be submerged, exposed to high-pressure water jets or left outdoors in the rain.

History, alerts and scenes: Through a Zigbee hub and the eWeLink app you can review temperature history, receive alerts for abnormal temperatures and create automations based on temperature changes.

Good to know
- A Zigbee 3.0 hub is required.
- The display unit works from -10°C to 60°C; only the probe goes down to -40°C and up to 115°C.
