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.


Measures active energy, voltage, current, active power, power factor, and grid frequency (optional: reactive energy and reactive power). Shows active energy consumption with a clear digital screen. Pulse LED: Indicates energy metering pulses. Power LED: Shows power supply status. Supports wired RS485 networks for remote meter reading and centralized management. Compatible with MODBUS-RTU or DLT645 protocols. Configurable with LoRaWAN/NB-IoT/4G/WiFi modules for flexible IoT connectivity.

HKT LoRaWAN Siren makes light and sound to tell the guard management there is an alert. It supports standard LoRaWAN protocol. It has high detection accuracy. With a durable shell, it has a long life span.

Up to 5Km communication range in an open environment; LCD Screen indicates reading, power percentage, allowance, valve, and signal status. Long-lasting battery life of up to 3 years; Capable of saving over 10,000+ historical operation records locally; Compatible with standard LoRaWAN® gateways and third-party network server platforms; Fast connection with HKT LoRaWAN® gateway and cloud platform without additional configuration.


Our LoRaWAN parking sensor uses dual detection (geomagnetic + 24GHz radar) with 99% accuracy. It checks space occupancy periodically and sends data to nearby LoRaWAN gateways, which forward it to the cloud. Facility managers can then view real-time space status from anywhere — no need to send staff for regular patrols. Used in underground garages, commercial complexes, and high-end residential projects.
Our LoRaWAN parking sensor features an NRC 0.88 (ISO354‑certified) sound absorption rating, which effectively reduces vehicle noise in underground garages and improves the acoustic comfort of enclosed parking areas.


Our parking space sensors help improve the efficiency of parking management through collcting and transforming the data of parking space.
