Abstract-In recent years, the integration of Internet of Things (IoT) technology in the healthcare sector has enabled continuous and remote monitoring of patient health. This project presents the design and implementation of an IoT-based real-time health monitoring and alert system using Arduino, aimed at enhancing patient care and emergency response. The system utilizes sensors such as a heart rate sensor, temperature sensor, and oxygen (SpO₂) sensor to continuously monitor vital signs. These parameters are collected by an Arduino microcontroller and transmitted via a Wi-Fi module (such as the ESP8266) to a cloud server or web dashboard in real-time. If any parameter crosses a critical threshold, the system instantly triggers an alert via SMS, email, or buzzer, ensuring timely medical intervention. The proposed solution is cost-effective, portable, and scalable, making it suitable for home care, hospitals, and remote health centers. It contributes to the growing need for smart healthcare solutions by offering real-time insights and immediate alerts, potentially saving lives through faster response times.
