Overview
A four-layer system built end to end. An Arduino-based wearable written in C++ runs an Edge Impulse-trained fall-detection model on-device through EloquentTinyML, streaming from accelerometer and gyroscope sensors; a Node.js API with JWT auth, Joi validation, helmet, and rate limiting ingests events and triggers alerts; and a Next.js dashboard gives caregivers live monitoring. One of the few student projects where hardware, embedded ML, and web engineering all had to work together.
