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.
