What Is a Battery Powered LoRaWAN DTU?
A LoRaWAN DTU (Data Transmission Unit) is a communication device that connects traditional serial devices to a LoRaWAN wireless network.
Many industrial sensors already use:
communication interfaces.
However, these sensors usually require wired communication cables.
