Industrial measurement system with LoRa interface

Abstract

Measurement, monitoring, and controlling various process parameters is a practice that has been prevalent in the manufacturing industry for the past few decades. Numerous measurement instruments which are available in the industry suit only a particular application requirement. Thus, multiplexing of a measurement device has many advantages over a single parameter measurement device. Wireless connectivity with the application infrastructure has always been desirable since the advent of IoT. This paper showcases the design process for the development of such a multiplexed measurement system, that will be compatible with a wide range of applications, with minimal installation space and cost, and which can communicate with the IoT network with the help of a LoRa module. LoRa, a wireless modulation method, enables low-power devices to communicate across long distances and low bit rates. The design of industrial measurement with LoRA interface aims to be a portable stand-alone embedded system, with an attractive and easily interpretable Graphical User Interface (GUI).
