Aplicativo para controle de velocidade angular utilizando MQTT como protocolo de comunicação

Abstract

In times of extraordinary events, such as pandemics, wars, and radical changes on our planet, we face the need for increasingly rapid and optimized adaptation. One of these necessary adaptations can be seen in the practical Linear Control classes at the Federal University of Uberlandia, held in the Mechatronics Teaching Laboratory, which are essential for applying the theoretical knowledge acquired during the course. To minimize the impact on students during periods of social instability, such as those that occurred during the COVID-19 pandemic, a solution disseminated by Industry 4.0 can be conceived. Utilizing an Industrial Internet of Things (IIoT) architecture, which allows us to connect various devices, sensors, and machines in real-time and remotely, generates profitability and reliability in diverse situations. Applied together with other tools like the Message Queuing Telemetry Transport (MQTT) protocol, it enables communication between networkconnected devices. Considering these tools as focal points, this project presents a solution that allows for the remote execution of the entire practical module of the discipline by controlling experiments through a mobile application, which is, in turn, highly adaptable to other environments outside the academic sphere. Complementing this architecture, we have ESP32 microcontrollers for controlling the practical prototypes and communicating with the local MQTT broker and the mobile application.
