Sistema de medição de potência aplicado ao ciclismo

Abstract

Cycling in Brazil has been growing rapidly, driven by the success of athletes like Henrique Avancini and the increase in recreational practitioners, making it the most practiced sport in Brazil, according to Strava reports. However, the national market still relies on the importation of accessories, such as power meters. This work aims to develop a low-cost prototype of a power meter, using ESP-32 and strain gauges to measure power and cadence during exercise and send data to a mobile device via Bluetooth Low Energy. Validation of the device was performed in internal and external tests, experiencing real conditions of use and obtaining power and cadence measurements as expected for an amateur cyclist. This multidisciplinary project integrates concepts from Computer Engineering to propose an affordable solution for Brazilian cyclists.
