This project presents the development of a GSM-based health monitoring system using Arduino, designed to enhance patient care through real-time tracking and remote diagnostics. It integrates heart rate, temperature, and oxygen saturation sensors to continuously monitor vital signs, making it suitable for hospitals, elderly care, and home-based applications. The system displays readings on an LCD for local observation and transmits data via a GSM module to a mobile number or cloud server, ensuring remote accessibility. A buzzer alerts caregivers when any parameter exceeds safe thresholds, enabling prompt medical response. The GSM module serves as the communication backbone, facilitating SMS alerts and bridging the gap between patients and healthcare providers. The system's modular design, centered around Arduino, allows for scalability and future upgrades such as cloud integration or mobile app support, highlighting the role of GSM technology in modern, accessible healthcare solutions.
