Integration framework for sensor through IoT embedded microcontroller in automation system for hydrogen generator management

Abstract

This paper presents a framework to integrate a traditional sensor within an Industry 4.0 featured automation system through an Internet of Things (IoT) embedded microcontroller. In particular, an Arduino microcontroller is connected to a water level sensor required for the performance of a hydrogen generator. By means of the IoT communication protocol Modbus TCP, the signal of the sensor is sent to an industrial programmable logic controller that automates the operation of a Smart Microgrid where the hydrogen generator is fed by a photovoltaic array. The developed system is described concerning hardware, software and communications, together with experimental results.
