Desenvolvimento de uma aplicação IoT para bancada didática de eletropneumática

Abstract

The evolution of Industry 4.0 and the Industrial Internet of Things (IIoT) has transformed manufacturing and educational environments, demanding efficient, flexible, and accessible connectivity solutions. In this context, the Message Queuing Telemetry Transport (MQTT) protocol stands out as a fundamental tool for enabling real-time communication with low bandwidth consumption between different devices. This work presents the development of a web server for the remote control and monitoring of an electropneumatic test bench, aiming at the modernization of laboratory practices in the Hydraulic and Pneumatic Drive Systems course. The system architecture is composed of a NodeMCU ESP8266 development board, responsible for valve actuation and sensor reading on the bench; a Raspberry Pi single-board computer, acting as the central server hosting the application developed in Python (Flask) and the MQTT broker; and a responsive graphical interface that allows operation in manual and sequential modes. The obtained results validate the application of open hardware technologies and protocols in the creation of robust educational tools, demonstrating the technical feasibility of remote control and monitoring via a communication network.
