Health Monitoring Wearable

A smart wearable device for tracking vital signs and activity levels.

Technical Details

This project involved designing a custom PCB for a wearable device that includes PPG and ECG sensors for heart rate monitoring and an accelerometer for activity tracking. The firmware, written in C for a Nordic nRF52 series SoC, processes sensor data and transmits it via Bluetooth Low Energy (BLE) to a companion mobile application. The mobile app, developed using Flutter for cross-platform compatibility, displays real-time data and historical trends, and includes features for setting health goals and receiving alerts.
