Abstract

ABSTRACT Health is an essential aspect of human life that can be monitored through vital signs, particularly heart rate and blood oxygen saturation (SpO₂). Monitoring these parameters is generally conducted intermittently in healthcare facilities, which does not provide continuous or real-time information about a person’s physical condition. In fact, heart rate and SpO₂ values may fluctuate due to physical activity, environmental conditions, or certain health disorders, highlighting the need for a practical self-monitoring system. This study aims to design and implement a heart rate and SpO₂ monitoring system based on the Internet of Things (IoT), integrated with the Telegram application as a platform for data display and early warning notifications. The system utilizes the MAX30102 sensor based on the Photoplethysmography (PPG) method to detect changes in blood volume, while an IoT microcontroller processes and transmits data to a Telegram server in real time. System testing was carried out by comparing sensor readings with standard medical devices to determine measurement accuracy, as well as evaluating data transmission performance in terms of speed and reliability. The results show that the system is capable of providing real-time monitoring with good accuracy and stable data transmission. This system has the potential to support remote health monitoring and early detection of abnormal conditions efficiently, providing useful preliminary information for users and healthcare personnel in making timely decisions.
