LoRaWAN contact tracing Wearable button

Contact Tracing Wearables

Wearable tracker for Covid19
Automated record close contact data
Social safety distance reminder
Real time reporting for user-defined SOS event
Easy to deploy of wearable device


LW004-CT is a LoRaWAN-Based network IoT device specifically designed for contact tracing purposes. It is compact, small in size, and easy to use. It can be used to track close contact and social safety distance reminder.

All of the close contact information will be obtained by scanning the incoming data from nearby BLE beacons or LW004-CT. And it will send these data to the nearest LoRaWAN gateway. The LoRaWAN gateway then transmits this data over to the cloud server. Once this data reaches the cloud, it is accessible all over the world 24/7.
