LoRa DTU
The ZW-LRT100 LoRa terminal is a product of LPWAN (Low Power Wide Area Network).
Based on LoRaTM spread spectrum modulation technology, terminals can communicate over ultra long distances. It has the advantages of concentrated power density and strong anti-interference ability. Outdoor measurement exceeds 6KM, providing RS232/RS485 interface with built-in 15KV ESD protection, low-power design, providing 5 channels of IO, capable of analog input and digital input and output, with IO direct drive relay function.
This product is widely used in the M2M industry in the IoT industry chain, such as remote meter reading, smart cities, smart buildings, smart firefighting, smart parking, smart homes, smart agriculture, and other fields.
