Description
Zigbee 3.0 Smart Temperature Sensor with LCD and Probe | Sonoff SNZB-02LD
◆ Zigbee 3.0 Smart Temperature Sensor with LCD and Probe - This device is not a motion sensor or a motion-activated light sensor. It is a temperature sensor designed for smart climate monitoring, equipped with an external probe for measuring temperatures in hard-to-reach or extreme environments.
🔥 Key Verified Features
✔ Zigbee 3.0 Connectivity
Connects to compatible Zigbee hubs (Sonoff ZBBridge, iHost, ZBDongle, NSPanel Pro, etc.) for smart readings and automation.
✔ External Stainless Steel Probe (1.5m)
Allows for temperature measurement in liquids, tanks, refrigerators, freezers, swimming pools, and other enclosed or challenging spaces.
✔ 2.2-inch LCD Display
Shows real-time temperature readings directly on the device without needing a phone.
✔ IP65 Water and Dust Resistance
Safe for use in splash and humidity-prone environments – ideal for bathrooms, outdoor areas, or kitchens.
✔ Long Battery Life (CR2477)
Powered by a replaceable CR2477 battery with a typical lifespan of approximately two years.

📌 What it IS and What it IS NOT
✅ It IS
◆ A Zigbee temperature sensor with an LCD screen and an external probe
◆ A device for real-time and app-based temperature monitoring
◆ Capable of automation based on temperature thresholds
❌ It IS NOT
◆ A motion detector
◆ A light sensor or presence sensor
◆ A humidity sensor (this model only measures temperature - not humidity )
🎯 How it Works in a Smart Home
◆ Pair the SNZB-02LD with a Zigbee hub/coordinator (e.g., Sonoff ZBBridge, iHost, ZBDongle series).
◆ Use the eWeLink app to remotely view temperature readings, set alerts, and trigger automations (e.g., turn on a heater if the temperature drops below a minimum).
◆ The probe allows for precise temperature sampling in liquids or internal spaces inaccessible to the main unit.
📍 Typical Use Cases
✔ Monitoring water tank temperature
✔ Checking refrigerator/freezer environment
✔ Greenhouse/gardening temperature data
✔ Tracking temperature in outdoor or humid areas
✔ Aquariums and pet enclosures
