ماژول پالس اکسیمتر MAX30100 (اندازه گیری ضربان و اکسیژن خون)

این ماژول شامل یک سنسور MAX30100 است که قابلیت اندازه گیری اکسیژن خون و ضربان را دارد . به نسبت اکسیژن موجود در خون ، رنگ خون می تواند روشن تر یا تیره تر باشد ، همچنین در هنگام انقباض قلب ، حجم و فشار خون در رگ ها افزایش و در هنگام باز شدن قلب این مقادیر کاهش می بیابد ، این تغییرات را می توان از طریق اندازه گیری میزان روشنایی خون به دست آورد که این اساس کار پالس اکسیمتر ها است .

Introduction

The MAX30100 is an integrated pulse oximetry and heart-rate monitor sensor solution. It combines two LEDs, a photodetector, optimized optics, and low-noise analog signal processing to detect pulse oximetry and heart-rate signals. The MAX30100 operates from 1.8V and 3.3V power supplies and can be powered down through software with negligible standby current, permitting the power supply to remain connected at all times.
