The increasing need for continuous health monitoring among elderly people has led to the development of smart healthcare systems. This paper presents a GSM-based elderly health monitoring system designed to track vital parameters such as body temperature, heart rate, and oxygen saturation (SpO₂) in real-time. The system uses biomedical sensors integrated with a microcontroller to collect patient data and transmit it through GSM technology to caregivers or medical professionals. In case of abnormal readings, the system automatically sends alert messages, ensuring immediate attention and reducing health risks. This solution is cost-effective, portable, and easy to use, making it suitable for home-based healthcare monitoring. The proposed system enhances patient safety, supports remote monitoring, and reduces the need for frequent hospital visits.
