Conceptual architecture definition: Implementation of a network sensor using Arduino devices and multiplatform applications through OPC UA

Abstract:

The implementation of devices or sensors developed over open source electronic platforms is a very important key of the projects aiming for promoting concepts such as Internet of things and Smart Cities. Due to the heterogeneity of these projects and especially the lack of a standard to regulate the communication process between the sensors and the application server, taking into account that many of the elements cannot be reused on similar infrastructure projects. This proposal considers an architecture based on the use of standard OPC UA and the use of messages MQTT to regulate the process of data transmission between the sensors and Supervisory Control and Data Acquisition systems available in the industry.
