HeartRateSPO2

介绍

生命体征监测仪,脉搏心率,血氧饱和度,血氧波形,使用MAX30102模块

开发环境支持:Arduino IDE,MicroPython

硬件支持:Raspberrypi Pico,Arduino Nano/Uno,ESP32,STM32

输入图片说明

软件架构

下位机硬件部分:Arduino IDE开发或者MicroPython开发支持硬件:Raspberrypi Pico,Arduino Nano/Uno,ESP32,STM32

上位机软件部分:Python 使用DearpyGui框架绘制桌面客户端

运行教程

  1. 单片机烧录程序
    • 使用ArduinoIDE烧录(HeartRate_SPO2_arduino/HeartRate_SPO2_arduino.ino/HeartRate_SPO2_arduino.ino)需要安装SparkFun_MAX3010x_Sensor_Library库。
    • 使用MicroPython(HeartRate_SPO2_micropython/*)注:该目录所有文件都需要上传到板子里。
  2. PC安装Python依赖库,在(HeartRate_SPO2/HeartRate_SPO2_PC)目录 pip install -r requirements.txt
  3. 运行上位机程序代码(HeartRate_SPO2/HeartRate_SPO2_PC/main.py),会自动识别可用串口,若串口设备较多识别的串口不正确,在窗口下方可以切换
  4. PC程序有socket服务,有连接时不间断发送数据,端口:9999,连接示例:(HeartRate_SPO2/HeartRate_SPO2_PC/client.py)

使用说明

  1. MAX30102连接电源,通过IIC连接单片机
  • Raspberrypi Pico 电路连接,使用Arduino IDE:IO4->SDA,IO5->SCL

Raspberrypi_Pico

  • Arduino Nano、Uno 电路连接,使用Arduino IDE:A4->SDA,A5->SCL,

Arduino_Nano

  • ESP32 电路连接:使用MicroPython:IO10->SDA,IO6->SCL,使用ArduinoIDE:IO8->SDA,IO9->SCL

ESP32_C3

  • STM32 电路连接,使用Arduino IDE:B7->SDA,B6->SCL

STM32F103

上位机数据格式

如果您的硬件在这里不支持(理论上可以用Arduino IDE编程的硬件都支持),或者自行开发,想适配本项目的上位机,可以用以下数据格式与上位机通信。

[DATA] red=XXX,ir=XXX,time=XXX

例如

[DATA] red=1000,ir=1000,time=1000

注:time的单位为ms

开发注意事项 :tw-1f61c:

  1. 使用Arduino IDE除了Nano/Uno外,Raspberrypi Pico、ESP32和STM32都需要安装对应的环境。
  2. 使用MicroPython需要预先烧录MicroPython固件。
  3. 使用Arduino IDE开发和使用MicroPython所使用的可能引脚不同,按需要修改。
  4. 环境安装方法百度有很多,实在装不上的话可以加个微信相互学习 :tw-1f61c:

使用注意事项 :tw-1f61c:

  1. MAX30102在手指按压时易触碰到模块上的外围电路引起干扰和短路,使用时需要将外围电路隔离,例如:贴胶带。
  2. MAX30102是反射式传感器,精度相较于透射式传感器略低,也会因手指按压力度影响测量结果,结果仅供参考,不能作为临床诊断依据。
  3. 如心率不准确,微调滤波器参数。
