Design and Development of Smart Bracelet System for Heart Health Monitoring Based on Internet of Things (IoT)

Abstract

Body health is essential for supporting various aspects of human life. In making a diagnosis, anamnesis (communication to obtain information about the disease) is followed by a physical examination, which includes general assessments. Key parameters for determining health conditions are heart rate, oxygen saturation, and body temperature. This paper presents the design of a Smart Bracelet Heart Health Monitoring System based on the Internet of Things (IoT) using Telegram for remote health monitoring. A quantitative experimental method was employed for system design and data analysis. The system's performance was compared with data from a Pulse Oximeter and a Thermogun. The Smart Bracelet Heart Health Monitoring System achieved heart rate measurements with an error margin of 3.8%, oxygen saturation with an error of 2.9%, and body temperature with an error of 2.7%. The measurement results are displayed on an OLED LCD and transmitted to Telegram. The system classifies patient status into three categories: Normal (heart rate > 80 BPM), Abnormal (heart rate 70-80 BPM), and Emergency (heart rate < 70 BPM). In case of an emergency or abnormal condition, data is automatically sent. Additionally, data can be manually sent by pressing a push button on the smart bracelet or sending the text "INFO" to the Telegram bot. The data transmission speed ranges from 2 to 22 seconds. The device also features GPS functionality with high positional accuracy.
