IoT based Medical Monitoring System using Node MCU

In recent years, there has been a wide use of internet of Things (IOT) technologies among health care system in offering real-time monitoring and remote access to patients’ health information. This project focuses on an IOT based medical monitoring system based on Node MCU which is a low-cost micro controller with onboard Wi-fi capabilities the system is optimizes to monitor on a real time basis important parameters of health including body temperature of oxygen in blood by utilizing sensors like DHT11, pulse sensor, and SpO2 sensor (MAX30100/30102). Collected data wirelessly transmits to platform like Think speak or Blynk upon and Ubi-dote stem which it become visible and remotely accessible for healthcare professionals as well as caretakers. The system also has alert mechanisms that inform users when any parameter goes out of normal ranges, allowing timely medical intervention. This solution seeks to improve patient care, especially for elderly or chronically ill patients, by allowing continuous and remote health monitoring in a cost-effective and scalable.
