Innovative Design of Internet of Things LoRa to Determine Radio Refractivity in Real-Time

Abstract

This paper aims to propose an Internet of Things (IoT)LoRa based system that determines radio refractivity in real-time. Our system consists of temperature and humidity sensor, LoRa gateway, LoRa shield, and Arduino UNO. ThingSpeak IoT platform is used to aggregate, visualize, and analyze live data streams using a numerical computing platform in the cloud. Real-time radio refractivity measurements will help network engineers when designing communication systems because the data obtained by this system are data specifically for that location, not the overall area. We have conducted the testing of our system for two days in the city of Sawangan, Indonesia and it succeded in obtaining real-time refractivity data.
