I need to remotely control a device, up to 5km open line of sight, to control a set of relays and a servo. For direct wired control I use Arduino Uno. For the remote control I tried to use nRF24L01 with Arduino but not much success.
My question is if a LoRa LSN50-V2 sensor could be used to communicate between the remote controller and the device. I am thinking to connect Arduino digital outputs to LoRa and communicate the signal to a receiver furnished on the device. Is this doable? Alternatively, what RC setup would be suitable for this application?
