随着人们健康意识的提高，如何实时监督老人健康是个大需求，智能老人健康监测手环作为一种新型的健康产品得到了广泛的关注。本设计介绍了一种基于stm32单片机的智能老人健康监测手环，并实现了相应的硬件和软件系统。该智能手环可以测量老人的心率、血氧

With the increasing awareness of health, real-time monitoring of the elderly's health has become a great demand. The intelligent elderly health monitoring bracelet, as a new type of health product, has attracted widespread attention. This design introduces an intelligent elderly health monitoring bracelet based on the STM32 microcontroller and implements the corresponding hardware and software system. The smart bracelet can measure the elderly's heart rate, blood oxygen, and steps and display them through a mobile APP and OLED screen; it supports setting heart rate threshold, time information timing, and heart rate alarm functions, making it easier for the elderly to drink water and take medicine in time. The heart rate timing can be set manually through the button module, and the buzzer will automatically sound when it exceeds the threshold. It also has the characteristics of real-time detection and display. The experiment proves that this intelligent bracelet design is novel, practical, and has good market prospects and promotion value.
