Real-Time BPM and SpO2 Monitoring Web System

This project implements a real-time health monitoring system that captures heart rate (BPM) and blood oxygen saturation (SpO₂) using a MAX30102 sensor connected to an Arduino UNO and displays the data on a web dashboard.

System Overview

• MAX30102 sensor captures BPM and SpO₂
• Arduino sends sensor data via Serial
• Flask backend receives and processes data
• MySQL stores time-series health data
• Web interface displays live vitals and graphs

Technologies Used

• Arduino UNO
• MAX30102
• Python
• Flask
• MySQL
• HTML, CSS, JavaScript

Project Structure

MySQL Database Storage

How It Works

1. Sensor captures BPM and SpO₂
2. Arduino sends values to backend
3. Flask processes and stores data
4. Web app displays live vitals

Notes

This project requires physical hardware and is intended to demonstrate real-time data acquisition, backend processing, and visualization.
