Health Monitoring System using Arduino with SMS Alert and Remote Access

Abstract The increasing demand for efficient healthcare solutions has led to the development of innovative
monitoring systems, particularly for the elderly and patients in remote areas. This paper presents a health
monitoring system that uses biomedical sensors and leverages the Internet of Things (IoT) technology to provide
real-time patient health data with SMS alerts and remote access capabilities. The system uses an Arduino UNO
microcontroller along with vital sensors, including a pulse oximeter for measuring blood oxygen levels, a
temperature sensor for monitoring body temperature and some different sensors. Data are transmitted securely
using an ESP8266 WiFi module, enabling access by healthcare professionals from any location. In addition, the
integration of a GSM module facilitates immediate alerts in critical situations, thereby ensuring timely medical
intervention. The system offers an innovative, low-cost, and portable solution that enhances patient monitoring,
reduces the need for physical consultations, and enables proactive healthcare management. With tested accuracy
rates of 98.5% for pulse rate measurement and 99.3% for body temperature detection, the proposed system
provides a robust framework for modern health diagnostics and monitoring.
