LoRaWAN SMART WRISTBAND (WB-100)

HKT WB-100 LoRaWAN smart wristband is small, lightweight, comfortable, and waterproof — suitable for everyday, long‑term wear. Integrated with LoRaWAN® and GPS technologies, it collects location and health data (heart rate, blood pressure, etc.) and sends them to the cloud via LoRaWAN gateways. Users and caregivers can view real‑time position and vital signs remotely, while the SOS button enables immediate emergency alerts. No cellular network needed — works for elderly care, worker safety, outdoor activities, and daily health monitoring for individuals and families.
