Sonoff Zigbee motion sensor, a Sonoff's 2020 new product, is Zigbee protocol based very tiny motion sensor. When used together with Sonoff Zigbee Bridge, can also switch WiFi-based other Sonoff devices via eWeLink cloud based on the detected movement.

Zigbee support the mesh network topology, so the Zigbee range can be extended by plug-in other Zigbee devices, such as Sonoff Basic Zigbee (ZBR3), acting as a Zigbee router.

One-tap pairing with Sonoff Zigbee Bridge or other compatible Zigbee gateways.

This ZigBee motion sensor is an extra-handy smart device for placing anywhere in your home to detect motion and trigger alarms. That means the sensor will send an instant alert notification to your mobile phone whenever the motion is detected if this security system is armed. If you have a SONOFF ZigBee Bridge, you can connect the sensor to it to activate Wi-Fi devices, not only ZigBee devices. For example, you can set a scene for your living-room light so that it will automatically turn on when you walk through the living-room. The new camera feature is used to make you know who is approaching your home and capture the video ever earlier than before. Boasts 110°view field and 6m detection rang and you can early receive an alert message of someone’s presence, accordingly taking measures to reduce the possibility that your house is threatened. Shared control is available for multiple users to check and monitor your home together. Easy and tool-free installation, 3M adhesive installation significantly saves your time. Powered by the battery which is convenient to stick it on any place that you want to monitor.

Want your light to turn on automatically when you go into the hallway? Simply set a smart-scene to activate your home in the action.

Can provide detection distance of up to 6M and angle of up to 110° when the sensor works, ensuring the suspicious motion near your house is detected even earlier.

Low-battery notification: You will get a notification of low-battery level when the battery life gets 10% remaining.

Simply use our included 3M adhesives to get the motion sensor mounted in your ideal locations just in seconds.

Trigger mechanism: There are two ways for the SNZB-03 triggering:

  • No motion is detected: When the motion is detected, after one minute of unoccupied movement "no motion detected" is triggered. (You will not receive the push notification for the "no motion detected" on the app, but it can take effect as a trigger condition in the smart scene.)
  • Motion is detected: The next trigger can be activated if there is no motion detected within one minute after the previous detection.
