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.

LoRaWAN Embedded Parking Sensor

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.

LoRaWAN SOLENOID VALVE CONTROLLER

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.
