Design of Portable Heart Rate and Blood Oxygen Detector
Abstract
With the increasing emphasis on health management, heart rate and blood oxygen saturation, as key indicators reflecting the basic health status of the human body, have become important demands for real-time and accurate monitoring in daily health monitoring. Especially in sports and fitness, daily health care, and specific population health management scenarios, timely monitoring of heart rate and blood oxygen changes is of great significance for preventing health risks and ensuring physical health. Therefore, it is necessary to develop a convenient and accurate portable heart rate monitoring device.
This design proposes a portable heart rate and blood oxygen detector based on STM32F103C8T6 microcontroller. The core functions of the system include: real-time collection of users’ heart rate and blood oxygen saturation data through the MAX30102 heart rate and blood oxygen detection module; With the help of OLED display screens, the measured heart rate and blood oxygen values are clearly presented, making it convenient for users to visually view; The system can preset the normal range thresholds for heart rate and blood oxygen. When the detected heart rate or blood oxygen values exceed the set maximum value or fall below the minimum value, the sound and light alarm function will be immediately activated to remind users to pay attention to their health status in a timely manner; At the same time, the system can stably send the collected heart rate and blood oxygen data to the mobile phone through the ECB02 Bluetooth module, which facilitates long-term storage, historical query, and health trend analysis of the data for users.
The application value of this portable heart rate and blood oxygen detector lies in providing users with a miniaturized, easy to carry, and easy-to-use health monitoring tool. By real-time monitoring, abnormal alarms, and wireless data transmission, it helps users to keep track of their own health status at any time, discover potential health hazards in a timely manner, provide data support for daily health management and timely medical treatment, and thus help improve users’ health management efficiency and quality of life.
