LoRaWAN sensor hub UC50 series

NB-IoTwith RS-485 interfaceModbus RTU

Overview
The UC50x series is a field‑deployable, multi‑interface controller for connecting and managing environmental and industrial sensors in harsh outdoor conditions. It supports GPIO, analog inputs, RS232/RS485, SDI‑12 and offers IP68 protection, multiple power options (battery, solar, DC) and quick NFC configuration. The device provides local storage, retransmission and integration options for cloud platforms to ensure reliable data acquisition and traceability.
