Parameter Monitoring and Alarm System for Health

Under the background of modernization, people ‘ s health problems urgently need attention, so an intelligent parameter monitoring and alarming system for health was designed. The system used STM32$\Gamma$407 as the core MCU control, together with temperature sensor DS18B20 and blood oxygen and heart rate monitoring module MAX30102. It could view the human health status on the LCD screen. The system monitored the human body every 5 seconds, measureing heart rate, body temperature and blood oxygen, and started the alarm function when the parameter thresholds was exceeded. The alarm relied on Fibocom L610 to send a distress signal to the outside world. After 12 sets of data tests of 10 testers, the standard deviation of parameters measured by the system was less than 0.76, the data error rate was less than 0.008, and the error value was controlled within ± 0.5. All alarm tests were successful. Above all, the system could stably and accurately measure physiological parameters and give alarm reminders.
