Smart Health Guardian: IOT-Based Real-Time Remote Health Monitoring System

This project presents a low-cost, real-time health monitoring system using an ESP32 microcontroller, designed to continuously track critical health parameters such as heart rate/pulse rate, and body temperature. The system integrates biomedical sensors and displaying real-time data.A core feature of this system is its abilityto detect abnormal health conditions and immediately send SMS alertsto predefined family members. This is achieved using internet connectivity via ESP32 and IFTTT Webhooks to trigger SMS through the IFTTT platform. The alert system ensures that caregivers and family members are notified in real time, enabling quicker response and better patient outcomes.This project is ideal for remote health monitoring, especially for elderly or chronically ill patients, and is a step forward in building smart healthcare systems using IoT (Internet ofThings) technology.
