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.
LoRaWAN Smart Wristband combines ultra‑low power consumption, long battery life, and instant SOS emergency alerts — delivering reliable safety monitoring for construction sites, elderly care, outdoor adventures, and everyday personal use. We offer OEM/ODM customization and long‑term after‑sales support — welcome to inquire!

Our smart wristbands feature GPS, Glonass, and BLE multi-mode positioning, enabling seamless indoor and outdoor location tracking even in remote areas or cellular dead zones. Engineered with multi-dimensional health monitoring capabilities (heart rate, blood pressure, and body temperature), motion sensing, and wearing detection, the wristband delivers continuous, real-time safety monitoring. Equipped with a one-touch SOS emergency button, an IP67 waterproof enclosure, ultra-low power consumption, long battery life, and a replaceable strap, it provides round-the-clock protection with added convenience for daily wear.
Features
Integrated GPS/Glonass dual‑satellite positioning + BLE 4.2 + motion sensors enable seamless indoor/outdoor location tracking; real‑time health monitoring covers heart rate, blood pressure, body temperature, pedometer, and sleep patterns.
Features SOS one‑key alert and wearing detection (auto‑switches to ultra‑low‑power mode when not worn); built on LoRaWAN® with resume transmission at breakpoints (caches up to 5 recent data records) to ensure data integrity even during network instability.
Available in LoRaWAN, NB‑IoT, CAT‑M (eMTC), 4G CAT1, and BLE‑only versions — with configurable positioning priority and reporting intervals for flexible deployment across diverse use cases.

HKT SVC-100 LoRaWAN Solenoid Valve Controller controls two valves independently via dual solenoid interfaces. Users can switch valves on/off or adjust flow remotely through the cloud platform — no need to be on site. Commands are sent from the user's device to the cloud, then down to the controller through LoRaWAN gateways. The controller also supports local configuration via Bluetooth for initial setup or manual override. It works with most water and air valves, making it useful for agricultural irrigation, smart gardens, and similar applications.
In smart building management, our IoT door locks help users ensure security and reduce operation costs.
