With the rapid development of science and technology and the improvement of people's quality of life, wearable devices have become an indispensable part of daily life. As a kind of wearable device, smart bracelets have been favored by the majority of users. The bracelet has multiple functions, such as health monitoring, positioning, time display, etc., providing users with a convenient life experience and health management.

The smart bracelet project based on STM32 is designed to develop a smart bracelet with complete functions, stable performance and affordable price. The main control chip uses STM32F103RCT6, which has the advantages of high performance, low power consumption and easy development, providing a strong guarantee for the stable operation of the smart bracelet.

In order to meet the needs of users for health monitoring, the bracelet project integrates functions such as blood oxygen detection, heart rate detection, and body temperature detection. These functions use special sensor modules such as MAX30102 and DS18B20 to ensure the accuracy and reliability of the measurement data. At the same time, in order to facilitate users to understand their own exercise conditions, the project also adds a walking step counting function, which realizes accurate step counting through the MPU6050 module.

In addition to the health monitoring function, the project also has a GPS positioning function, which can obtain the user's geographical location information in real time. This is of great practical value for outdoor sports enthusiasts and families who need to keep an eye on the whereabouts of children or the elderly.
