Product Introduction
LW004-CT is a LoRaWAN-Based network IoT button 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. With a panic button can be used
for SOS function or user-defined the panic event.
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 to all over the world
24/7.
