IoT-Enabled Smart Health Monitoring and Medical Care System for Better Well-Being

Abstract

A smart health monitoring system that implements the MAX30100 pulse oximeter sensor, temperature sensor, OLED display, and ESP8266 Wi-Fi module has been designed and developed to monitor critical vital signs in real time. The system measures pulse rate, SpO2, and body temperature when connected to a human subject, displaying the results on an OLED screen. If the body temperature exceeds 100°F, the system triggers a health warning advising to "Contact with doctor" and after a brief countdown, suggests a common antipyretic medication, e.g., Paracetamol. The device uses threshold-based logic and conditional display responses to simulate a basic automated care system. This project emphasizes the integration of cost-effective embedded components to create a portable, low-powered health monitoring solution. It offers potential benefits in early health detection, especially in remote or underserved areas. The system also lays the groundwork for future expansion with cloud connectivity, mobile alerts and personalized healthcare recommendations, thus supporting broader applications in remote patient monitoring and IoT-based medical care.
