Sonoff Temperature Humidity Splash Proof Sensor (Zigbee)

This sensor features a large, easy-to-read LCD screen that displays current temperature and humidity levels. It’s built with IP65 splash-proof protection, allowing it to function reliably in damp environments like bathrooms, kitchens, or near windows. The sensor updates readings every 5 seconds, ensuring accurate and timely data.

It pairs with Sonoff Zigbee hubs such as the Zigbee Bridge Pro, NSPanel Pro, iHost, and ZBDongle-E, and is also compatible with Alexa Zigbee and SmartThings. Users can create automation scenes—for example, turning on a fan when humidity rises or activating a heater when temperature drops.

Powered by a CR2450 coin cell battery, the SNZB-02WD offers low power consumption and long battery life. It supports wall mounting and includes adhesive backing for easy installation.
