Which motion sensor do you need?
⚡ Key Features
- Wider 120° Detection Angle — covers more of the room than the Gen1's 110°; 6 m PIR range with fast ~5-second response
- Adjustable Sensor Head — aim the detection zone exactly where you want it; pairs with the included magnetic base for easy repositioning
- Adjustable Cooldown (5–60 s) — tune how often the sensor re-triggers to minimise false activations and save battery
- Independent Lux Sensor — light-based automations with calibration and up to 6 months of illumination history
- 3-Year Battery Life — single CR2477 coin cell (included); low-battery alert in the eWeLink app
- Smart Scene Automations — "Motion detected → lights on", "No motion for 5 minutes → lights off", "Motion after 10 PM → security alert"
- Local Zigbee Scenes — motion-to-light automations keep working through your hub even when the internet is down
- Flexible Mounting — magnetic attachment, screws or adhesive; walls, ceilings or shelves at any angle
- Home Assistant — supported in ZHA and Zigbee2MQTT; exposes occupancy, battery and illuminance (lux) entities
🏠 Perfect For
Automatic Hallway Lights
Walk past → lights on. Leave → lights off after your chosen timeout. The adjustable head lets you aim the zone down a passage precisely.
Security Alerts
"Motion in the garage after 11 PM → push notification + camera recording." Combine with SNZB-04P door sensors for a complete Zigbee security zone.
Lux-Aware Lighting
Only trigger lights when it's actually dark — the calibrated lux sensor plus illumination history makes day/night automations reliable.
Office Energy Saving
No motion in the meeting room for 15 minutes → lights and aircon off. The longer cooldown options reduce pointless re-triggers.
