Application of Wi-Fi and LoRa Technologies for Wireless Measurement of Physical Quantities

Abstract

In this paper we present a brief description of existing wireless data transmission technologies used in the Internet of Things (IoT) and the Internet of Industrial Things (IIoT). Then we consider the application of Wi-Fi and LoRa technologies for wireless measurement and monitoring of physical quantities (really they are the parameters of the evaporation duct - air temperature, humidity and atmospheric pressure). The system contains wireless sensing nodes (beacons) and the unit for host-centric processing and storage of data. We provide test results of a comparison of Wi-Fi- and LoRa-based implementations.
