Sonoff SNZB-03
What is SONOFF SNZB-03?
SONOFF SNZB-03 is a Zigbee motion sensor designed to detect movement and trigger smart home automations. It uses Zigbee wireless communication to send motion alerts or activate smart scenes through a Zigbee hub. The device operates using a CR2450 3V battery and detects motion within a range of up to 6 meters with a 110° detection angle.
Key Benefits
- Detects motion instantly to trigger smart home automations.
- Wide 110° detection angle with up to 6 m detection range.
- Battery-powered design with CR2450 3V battery.
- Supports smart scene automation through a Zigbee hub.
Why Use SONOFF SNZB-03?
It is designed to detect human motion and trigger automations or alerts in a smart home environment. When movement is detected, the sensor can activate smart scenes such as turning on lights or sending notifications through a connected Zigbee gateway.
The sensor uses the Zigbee wireless protocol (IEEE 802.15.4) to communicate with compatible Zigbee hubs. This allows the device to operate as part of a smart home automation system without relying on direct Wi-Fi connectivity.
It is compact and easy to install using adhesive mounting, allowing placement in hallways, entrances, or other areas where motion detection is needed. The device can trigger automations such as lighting control or security alerts when motion is detected.
