Sonoff SNZB-02P: Zigbee Temperature and Humidity Sensor
The SNZB-02P is an upgraded version of the SNZB-02, designed as a low-power, high-accuracy temperature and humidity sensor. It supports Zigbee 3.0 protocol, ensuring broad compatibility with multiple Zigbee gateways such as SONOFF iHost, NSPanel Pro, ZB Bridge Pro, ZBDongle-E, and Zigbee-enabled devices like Amazon Alexa with integrated Zigbee hub.
Precision Sensing with Fast Data Updates
At its core, the SNZB-02P incorporates a high-precision Swiss-made sensor, delivering temperature accuracy of ±0.2°C and humidity accuracy of ±2% RH. The sensor updates readings every 5 seconds, keeping you informed of the latest environmental changes in real time. You can also configure comfort alerts to notify you instantly on your smartphone if the room’s temperature or humidity goes beyond your predefined comfort range—helping maintain a healthy and comfortable environment at all times.
Cloud-Based Historical Data and Export Options
The device supports cloud storage, retaining up to six months of temperature and humidity data. Through the app, users can view environmental trends daily, monthly, or every six months via real-time queries. This data can also be exported, enabling you to track patterns and optimize your indoor climate based on long-term insights.
Flexible Installation Options
The SNZB-02P offers three mounting methods for versatile placement: using 3M adhesive, 3M adhesive with a metal plate, or screw mounting. Place the sensor in various indoor spaces such as living rooms, bedrooms, nurseries, greenhouses, reptile enclosures, or equipment cabinets for remote monitoring of environmental conditions.
