MWB02 Wearable Panic Button
A rechargeable wearable panic button built on the Nordic nRF54L15 chip with Bluetooth 6.0, designed as a reliable emergency button for critical environments and high-risk zones. It combines a persistent SOS alert, Bluetooth anchor scanning for positioning support and an onboard event log for traceable review. It features LED and haptic (vibration) confirmation, rugged IP67 protection and a 260 mAh battery with magnetic charging and an included dock — delivering practical safety value in healthcare and industrial environments.
The MWB02 keeps broadcasting the distress signal continuously until physical help arrives — with no signal gaps. The alert does not depend on a single transmission that may be lost.
Highlights
- Bluetooth 6.0 (Nordic nRF54L15 chip / nRF54 series)
- Persistent SOS, no signal gaps (continuous broadcast until help arrives)
- Traceable onboard event log (with timestamps)
- High-accuracy positioning through Bluetooth anchor scanning
- Switchable scanning modes (active scanning / low-power tag) for longer runtime
- Two-way confirmation: 7-color LED + haptic vibration motor
- Rugged IP67 protection
- Magnetic charging with included dock
- Multiple wearing options (wristband, lanyard, helmet, chest, armband and more)
How It Works
When pressed, the MWB02 triggers an instant SOS alert, confirmed by vibration and light, and starts transmitting location and events continuously. The device scans nearby Bluetooth anchors to support positioning and reports motion and button events with a timestamp, while keeping a copy of the records in internal storage.
Features / Capabilities
