基于单片机的人体生理状态监测系统的设计(附电路图)(论文10600字)
摘要：生活水平提高，人们越来越关注自身的健康状况。人体突发疾病或隐藏的慢性疾病会引起体温、心率的异常变化，为了便于对人体生理状态的监查，本文设计了基于STC89C52RC单片机的人体生理状态监测系统。系统基于STC89C52RC单片机由Pulse Sensor、DS18B20、ADXL345传感器分别监测人体心率、体温和运动步数，传感器把检测的数据传输到单片机中，通过电路和HC-05传输到LCD1602或手机界面进行实时显示。系统实验结果证实了该系统的能有效监测人体心率、体温和步数。

Human physiological condition monitoring system based on  Microcontrollers
Abstract:As the standard of living improves, people are paying more and more attention to their own health. Human body sudden illness or hidden chronic diseases can cause abnormal changes in body temperature and heart rate. In order to facilitate the examination of human physiological state, this paper designs a human physiological condition monitoring system based on STC89C52RC microcontroller. The system monitors the heart rate, body temperature and motion status of the human body by Pulse Sensor, DS18B20 and ADXL345 based on STC89C52RC. The sensor transmits the detected data to the MCU, and transmits it to the LCD1602 or mobile phone interface for real-time display through the circuit and HC-05. Systematic experimental results confirmed that the system can effectively monitor human heart rate, body temperature and number of steps.
