From the project

Este es el repositorio dedicado al proyecto del wearable para Capstone 2026-1 G10

SupaClock es un sistema de salud inteligente usable (wearable) de pulsera desarrollado como parte del curso IEE2463. Su propósito es capturar biometría crítica en tiempo real, procesarla tanto en el dispositivo mediante técnicas de Inteligencia Artificial en el borde (TinyML), enviarla vía Bluetooth Low Energy (BLE) a una aplicación móvil de compañía y respaldarla de forma segura en la nube.
