Sonoff Temp and Humidity Sensor (Zigbee)

Product Introduction

The Sonoff Temp and Humidity Sensor (Zigbee) is a compact smart environmental sensor designed to monitor temperature and humidity levels in real time. Using Zigbee 3.0 connectivity, the sensor communicates with a compatible Zigbee hub to provide accurate environmental data for smart home monitoring and automation.

By continuously measuring indoor climate conditions, the sensor allows users to track changes in temperature and humidity through the eWeLink smart home platform. These readings can also trigger automation routines that help maintain comfortable and efficient living environments.

Battery-powered and designed for flexible placement, the sensor can be mounted on walls, placed on shelves, or positioned in any room where climate monitoring is needed. Its compact design makes it an ideal addition to modern smart home ecosystems.

Key Features

Real-Time Temperature and Humidity Monitoring
Continuously measures environmental conditions to provide accurate temperature and humidity readings.

Zigbee 3.0 Wireless Connectivity
Uses Zigbee communication for stable, low-power connections with compatible smart home hubs.

Smart Automation Triggers
Environmental readings can trigger automation scenes such as turning on fans, humidifiers, or heating systems.

Compact Wireless Design
Small, lightweight sensor can be installed anywhere without wiring.

Long Battery Life
Powered by a coin-cell battery designed to last up to two years under normal usage.

Flexible Installation
Can be mounted using adhesive pads, screws, or placed on a flat surface.

Smart Home Integration

The Sonoff Temp and Humidity Sensor connects to Zigbee hubs such as:

• Sonoff Zigbee Bridge Pro
• Sonoff Zigbee Bridge Ultra
• Sonoff iHost Smart Home Hub

Once connected, environmental readings can trigger automation scenes through the eWeLink smart home platform.

Common automation examples include:

• Turning on ventilation when humidity rises
• Activating heating when temperature drops
• Monitoring indoor climate conditions remotely
• Triggering smart alerts when environmental thresholds are exceeded
