便捷式健康监测系统设计：基于STM32单片机的心率计步体温监测展示

Bio-signal indicators are closely related to people's health and can only be more scientifically dealt with and improve the quality of life if the rules are more fully understood. With the development of science and technology, the technology of portable biomedical electronic devices is becoming more mature, and the demand for real-time monitoring and display devices for portable biomedical signals is also increasing as people's living standards continue to improve. There are many health indicators, but this design is based on the two important health indicators of the number of steps and the heart rate of walking. Therefore, this graduation design will develop a real-time monitoring and display system based on the STM32 microcontroller according to the current development needs. The motion real-time monitoring and display system mainly uses the STM32F103C8T6 core board circuit, and the detection of the number of steps, the distance traveled, and the walking status are mainly implemented by the gravity acceleration sensor ADXL345. The real-time detection of heart rate and body temperature is achieved through a heart rate sensor and a temperature sensor. The real-time display of the number of steps, distance, heart rate, and temperature is implemented through the LCD1602. Keywords: STM32F103 steps ADXL345 module heart rate module temperature.
