Real-Time Arduino-Based Health Monitoring System

is an advanced biomedical electronics project designed to monitor vital health parameters of a person continuously and in real time. The system uses medical-grade sensors such as heart rate sensors, body temperature sensors, and optionally blood oxygen (SpO₂) sensors to measure physiological signals accurately. An Arduino microcontroller collects and processes this data, providing immediate results that can be displayed on an LCD screen or transmitted wirelessly to a mobile app, computer, or IoT platform for remote monitoring. This allows caregivers, patients, or researchers to track health status without manual intervention. The system features low power consumption, a compact and portable design, and reliable, accurate readings suitable for continuous use. It is widely applied in basic healthcare monitoring, patient observation, fitness tracking, telemedicine, and educational demonstrations. This project helps students and professionals understand embedded system programming, sensor interfacing, real-time data processing, and wireless health monitoring, making it an ideal tool for biomedical engineering education, IoT-based health applications, and academic research.
