  Overview

  SNZB-02WD is a Zigbee LCD smart temperature and humidity sensor designed with a unique structure. The core sensor is protected by an IP65-rated housing and detects external temperature and humidity through an internal waterproof, breathable membrane, ensuring reliable performance even in humid or misty environments. This makes it ideal for use in places such as windows and gardens to monitor external conditions. SNZB-02WD features a 2.2-inch LCD screen that clearly displays temperature and humidity. It withstands UV radiation, ensuring long-term durability even under direct sunlight, and is capable of measuring temperature in low-temperature environments, and is capable of measuring temperature in low-temperature environments. With an accuracy of ±0.2℃ for temperature and ±2% RH for humidity, it provides near-instant and reliable data. SNZB-02WD supports Zigbee hubs using the Zigbee 3.0 protocol, including devices like SONOFF iHost, NSPanel Pro, ZBBridge-P, ZBBridge-U, ZBDongle-E, ZBDongle-P, Echo 4th Gen, Echo Show 2ndGen, and Echo Plus 2nd. *Note: Amazon Hub doesn't support humidity monitoring. SNZB-02WD can also be integrated into open-source platforms such as Home Assistant via the SONOFF ZBDongle series, allowing you to create your own customized temperature/humidity management solutions. With the eWeLink app, you can view temperature and humidity data by day, month, or up to the last six months, with a storage capacity of up to 180 days. You can access or export historical data, which helps you better understand your garden and optimize plant care. Create smart scenes through the eWeLink app, receive notifications for abnormal activity, or set up automation based on temperature or humidity changes. For example, you can receive instant notifications on your phone if a power outage causes a sudden temperature drop in your reptile tank. When the air becomes too dry, you can automatically activate the water valve for irrigation to maintain optimal garden humidity.
