Nplooj ntawv qhia no yuav qhia koj yuav ua li cas nqa tau yooj yim nqa 3-lead ECG/EKG monitor. Tus saib xyuas siv AD8232 pawg thawj coj los ntsuas ECG lub teeb liab thiab khaws nws mus rau hauv daim npav microSD rau kev tshuaj xyuas tom qab.

Cov khoom siv tseem ceeb xav tau:

5V rechargeable roj teeb

AD8232 pawg thawj coj tawm

Lub sijhawm tiag tiag - RTC DS3231 module

Micro SD daim npav module + micro SD daim npav

Micro-USB breakout

3.3V tswj

ECG ua + cov ntaub qhwv pov tseg

Resistors/capacitors/ATMega328 nti rau hloov pauv los ntawm Arduino Uno teeb tsa rau ATMega328 standalone-saib

Kauj Ruam 1: Xeem Cheeb Tsam thiab Code Nrog Arduino Uno

Lub kaw lus tuaj yeem sim ua ntej siv Arduino Uno. Hlau raws li qhia hauv daim duab. ECG cov kab hluav taws xob thiab cov ntaub qhwv tau txuas nrog AD8232 thiab yuav tsum tau muab tso rau ob sab ntawm lub hauv siab nrog hauv av txuas txuas qis dua-saib nplooj sparkfun https://learn.sparkfun.com/tutorials/ad8232-heart-rate-monitor- hookup-phau ntawv qhia kom paub meej ntxiv. Ib daim duab Arduino uas tuaj yeem siv tau rub tawm ntawm no. Cov ntaub ntawv yuav tsum tau sau sai sai rau hauv daim npav SD kom tau txais lub teeb liab ECG raug. Kuv tau pom tias daim npav SD txuag lub sijhawm siv sijhawm ntawm 10s ntawm milliseconds (qee daim npav SD nrawm dua lossis qeeb dua). Txuag lub sijhawm tshiab taw tes rau SD daim npav ntawm txhua lub voj yog qeeb dhau vim peb xav tau tiag tiag kom tuaj yeem sau txhua ob peb milliseconds. Yog li cov cai muaj qhov tsis sib xws uas yuav sau 40 cov ntsiab lus ua ntej xa mus rau SD daim npav rau kaw. Cov ntaub ntawv raug khaws tseg ua semicolon cais cov ntawv txt. Peb kab ntawv qhia txog AD8232 cov zis, lub sijhawm los ntawm RTC module, thiab lub sijhawm los ntawm millis () ua haujlwm uas muab qhov tseeb ntau dua rau kev txiav txim lub sijhawm ntawm cov ntaub ntawv sib qhia.

Kauj ruam 2: Ua Portable Version

Txhawm rau ua kom lub tshuab txav mus los Kuv tau siv cov lus qhia hauv qab no https://dronebotworkshop.com/arduino-uno-atmega328/ los ua tus sawv cev ATMeg328 raws li qhov system nrog cov tiv thaiv, cov khoom siv hluav taws xob thiab quartz siv lead ua. Kuv tau siv 5V lithium roj teeb uas muaj roj teeb nrog lub micro-usb breakout board los muab lub zog ua ke nrog 3.3V tus tswj hwm kom muaj zog rau AD8232. Cov khoom siv sib txawv tau muab muag rau ntawm kab txaij.
