Design of home health monitoring system based on STM32

As people’s health awareness increases and medical costs continue to rise, home health monitoring is gradually becoming a focus of attention in people’s daily lives. The home health monitoring system can conveniently and quickly monitor human health data in real time to facilitate timely detection and prevention of diseases. A home health monitoring system based on STM32 is proposed in this paper, the system mainly consists of an STM32F103C8T6 microcontroller, a MAX30102 heart rate and oximetry sensor, a DS18B20 temperature sensor, an XGZP6847A pressure sensor and an LCD. Among them, the MAX30102 heart rate and oximetry sensor can detect heart rate and oximetry in real-time, the DS18B20 temperature sensor can detect human body temperature in real-time, the XGZP6847A pressure sensor can measure blood pressure value. The collected data are transmitted to the STM32 microcontroller through serial communication for processing and calculating heart rate, oximetry, body temperature and blood pressure, and the results are displayed on the LCD and uploaded to the mobile phone APP through the wireless module ESP8266. The experimental results show that this system has the characteristics of high precision, high sensitivity, low power consumption and fast response, which can achieve real-time detection and analysis of human health data and achieve better results. Meanwhile, this system has the advantages of small size, low cost and easy operation, which can be conveniently used for home health monitoring.
