摘 要
随着健康意识的提高，健康称已成为人们日常生活中不可或缺的一部分。本研究设计了一种基于STM32F103C8T6单片机的健康称系统，该系统通过超声波传感器获取用户的身高信息，利用HX711模块精确测量用户的体重。在此基础上，系统能够自动计算用户的BMI值，并根据BMI值判断用户的体重状况。当BMI低于18.5时，系统判定为体重过轻；当BMI在18.5至23.9之间时，系统判定为体重正常；当BMI高于24时，系统判定为体重过重。系统采用OLED显示模块，能够实时显示用户的身高、体重以及BMI值，方便用户直观了解自身健康状况。此外，系统还集成了WiFi模块，支持将监测数据实时传输至手机端，使用户能够随时随地关注自己的健康数据。实验结果表明，该健康称系统具有测量准确、操作简便、功能丰富等优点，为人们的健康管理提供了有力支持。

ABSTRACT
With the improvement of health awareness, health has become an indispensable part of people’s daily lives. This study designed a health scale system based on STM32F103C8T6 microcontroller. The system obtains the user’s height information through ultrasonic sensors and accurately measures the user’s weight using the HX711 module. On this basis, the system can automatically calculate the user’s BMI value and determine the user’s weight status based on the BMI value. When the BMI is below 18.5, the system determines that the weight is underweight; When the BMI is between 18.5 and 23.9, the system determines that the weight is normal; When the BMI is higher than 24, the system determines it as overweight. The system adopts OLED display module, which can display the user’s height, weight, and BMI value in real time, making it convenient for users to intuitively understand their own health status. In addition, the system also integrates a WiFi module that supports real-time transmission of monitoring data to mobile devices, allowing users to monitor their health data anytime and anywhere. The experimental results show that the health scale system has the advantages of accurate measurement, easy operation, and rich functions, providing strong support for people’s health management.
