The RS485-LN could be a RS485 to LoRaWAN convertor. It converts the RS485 devices into LoRaWAN wireless network that modify the IoT installation and reduce the installation/maintaining value. RS485-LN permits the user to watch / to monitor RS485 devices and reach extraordinarily long ranges. It provides ultra-long range spread spectrum communication and high interference immunity while minimizing current consumption. It targets skilled wireless sensing element network applications like irrigation systems, sensible metering, smart cities, smartphone detection, building automation, and so on. For information uplink: RS485-LN sends user-defined commands to RS485 devices and obtain the return from the RS485 devices. RS485-LN will method these returns in keeping with the user-define rule to urge the ultimate payload to transfer to LoRaWAN server. For information downlink: RS485-LN runs in LoRaWAN category C. once there downlink commands from LoRaWAN server, RS485-LN can forward the commands from LoRaWAN server to RS485 devices.
