摘要
随着人们健康管理意识的不断提升和对日常环境感知需求的增加，实时监测个人生理指标与周边环境参数成为提升生活质量的重要需求。对于关注健康的人群而言，心率、血氧等生理指标的异常若不能及时察觉，可能隐藏健康风险；同时，了解环境光照、大气压等信息，也能为日常出行与活动提供参考。因此，研发一款能集成多维度监测功能、便捷实用的智能设备具有重要意义。
本设计提出了一种基于 STM32F103C8T6 单片机的智能手环。系统主要功能包括：通过 MAX30102 模块实时检测当前用户的心率与血氧饱和度；借助 5516 光照检测模块获取当前环境的光照强度；利用 MPU6050 模块精准检测用户的运动步数；通过 BMP180 气压检测模块采集当前环境的大气压数据；所有检测数据均通过 OLED 显示屏清晰展示，方便用户实时查看；用户可通过按键灵活设置心率、血氧的正常阈值范围；当系统检测到心率或血氧超出预设阈值时，立即启动声光报警功能，及时向用户发出健康提醒。
该智能手环的作用在于，为用户提供了一款集成化、便携式的多参数监测工具。通过对生理指标与环境参数的实时监测、清晰显示及异常报警，既能帮助用户及时掌握自身健康状况，尽早发现潜在健康隐患，又能为日常活动与出行提供环境参考，助力用户提升健康管理效率与生活便利性。

Abstract
With the continuous improvement of people’s awareness of health management and the increasing demand for daily environmental perception, real-time monitoring of personal physiological indicators and surrounding environmental parameters has become an important requirement for improving the quality of life. For people who are concerned about their health, if physiological indicators such as heart rate and blood oxygen are not detected in a timely manner, they may hide health risks; At the same time, understanding information such as environmental lighting and atmospheric pressure can also provide reference for daily travel and activities. Therefore, it is of great significance to develop an intelligent device that can integrate multi-dimensional monitoring functions and is convenient and practical.
This design proposes an intelligent wristband based on STM32F103C8T6 microcontroller. The main functions of the system include: real-time detection of the current user’s heart rate and blood oxygen saturation through the MAX30102 module; Using the 5516 light detection module to obtain the current ambient light intensity; Using the MPU6050 module to accurately detect the user’s movement steps; Collect atmospheric pressure data of the current environment through the BMP180 pressure detection module; All detection data are clearly displayed on OLED screens, making it convenient for users to view in real-time; Users can flexibly set the normal threshold range of heart rate and blood oxygen through buttons; When the system detects that the heart rate or blood oxygen exceeds the preset threshold, it immediately activates the sound and light alarm function to promptly issue health reminders to the user.
The function of this smart bracelet is to provide users with an integrated and portable multi parameter monitoring tool. By real-time monitoring, clear display, and abnormal alarm of physiological indicators and environmental parameters, users can not only timely grasp their own health status, detect potential health hazards as early as possible, but also provide environmental references for daily activities and travel, helping users improve health management efficiency and convenience of life.
