With the rapid development of modern technology, personal health monitoring devices have become an indispensable part of people's lives. Especially in the field of fitness, medical treatment and daily health care, real-time monitoring of heart rate and blood oxygen saturation is particularly important. This study aims to design and develop a portable oximetry heart rate detector based on STM32 microcontroller. The device integrates the functions of blood oxygen and heart rate detection, temperature monitoring, step counting and wireless data transmission, using MAX30102 detection module for heart rate and blood oxygen measurement, DS18B20 temperature sensor for temperature detection, ADXL345 accelerometer sensor for step counting, and Bluetooth module to realize the wireless transmission of data. Through hardware design, software development and system testing, this study verifies the feasibility and practicality of the device and provides a new solution for personal health monitoring.
