Desenvolvimento de um sistema de telemetria e supervisório aplicado ao projeto URI Rally CAR

Abstract

The growing demand for smart automotive monitoring solutions has driven the development of embedded systems capable of collecting, transmitting, and interpreting data in real-time, especially in competition vehicles, where operational reliability is crucial for performance and safety. In this context, the present work proposes the development of a vehicular telemetry system applied to the URI Rally Car, an off-road prototype built by academics from the Integrated Regional University of Alto Uruguai and Missões (URI). The scientific relevance of this study lies in the implementation of a low-cost, highly accessible solution, contributing to the advancement of technologies applied to the academic and sports sectors, in addition to fostering research in the field of embedded electronics. The developed system enables the real-time monitoring of critical engine variables, such as oil temperature and pressure, utilizing automotive sensors integrated with an ESP32 microcontroller. Communication with the user occurs via Bluetooth, through an application created using MIT App Inventor, which presents the data on an intuitive Human-Machine Interface (HMI) and incorporates visual alerts for risk situations. The solution's validation included simulations on the Wokwi platform and practical bench tests, which demonstrated technical feasibility and stability in data reading and transmission. Furthermore, the physical adaptation of the sensors to the prototype, the definitive assembly of the electronic board, and the integration of the system with web platforms for remote data analysis were carried out. The developed telemetry system demonstrated satisfactory performance during testing, carrying out continuous collection of temperature and pressure variables and transmitting them stably to the mobile application via Bluetooth. The sensors showed good accuracy, and the ESP32 responded consistently to the readings, ensuring real-time updates. Additionally, cloud data transmission was implemented, enabling remote storage and monitoring through web platforms. The prototype also operated with low energy consumption and maintained a reduced overall cost, reinforcing its feasibility for academic projects and testing environments. Despite its limitations, the system proved to be functional, accessible, and suitable for basic monitoring in experimental vehicles such as the URI Rally Car.
