With the improvement of living standards, people pay more and more attention to health for both the elderly and the young. Only a good body can experience life, but how can the public better understand their physical and mental health? Electronic information technology and medicine are developing at the same time. The combination of the two can just solve people's health problems. Therefore, people have a greater demand for high-precision portable medical monitoring instruments. For this reason, according to the needs of the development of the times, a motion monitoring module based on MCU is designed.
This design is mainly composed of STM32 MCU circuit, adxl345 acceleration sensor, heart rate detection module circuit, OLED liquid crystal display circuit, power supply circuit, clock DS1302 and DS18B20 temperature sensor. Through adxl345 measurement of gravity acceleration, is used to judge the state of the human body, according to the numerical changes of the state of step counting function. Through the heart rate sensor test, through the finger pulse amplification, after the comparator processing, sent to the MCU for heart rate acquisition. The steps, heart rate, temperature and time are displayed on LCD1602. This design system has low price and cost, comprehensive functions and good market prospects.
KEY WORDS: STM32; Single chip microcomputer; DS18B20 temperature sensor; A pedometer; Liquid crystal display
