Smart Health Monitoring System

𝗢𝘃𝗲𝗿𝘃𝗶𝗲𝘄:

The Smart Health Monitoring System is an IoT-based healthcare solution designed using ESP8266 (NodeMCU) and biomedical sensors. This system can measure real-time Heart Rate (HR) and Blood Oxygen Level (SpO₂) using the MAX30100 sensor. The collected data is processed and displayed on a mobile application and cloud platform for remote monitoring.

The system also includes an intelligent alert mechanism that notifies users when abnormal health conditions are detected. Additionally, data is sent to cloud platforms for storage and analysis, enabling continuous health tracking. This project demonstrates IoT-based healthcare monitoring, real-time data transmission, alert systems, and cloud integration.
