ATTiny85 Pulse Oximeter with Photoplethysmogram (PPG) display

STM32 HAL driver for MAX30102 pulse oximeter and heart rate sensor. Not for clinical use – proceed at your own risk.

Simple SpO2 plotter from scratch for Arduno IDE by reading MH-ET LIVE MAX30102 raw RED/IR data

This pulse oximetry shield from ProtoCentral uses the AFE4490 IC to enable your Arduino to measure heart rate as well as SpO2 values.

A demo for the Oximeters with 4.0BLE inside.

Protocol for Bluetooth & USB Oximeters made by Shanghai Berry Medical

This project is MAX3010x library for STM32F4

A low cost medical monitoring system with ECG and Pulse oximeter for fun or educational use

Hardware repo for the Pulse Oximeter Heart Rate Sensor using Maxim Integrated ICs: the MAX32664 Bio Metric Sensor Hub and the MAX30101 Pulse Oximetry and Heart-Rate Module.

Heart Rate and Pulse Oximeter sensor. a MAXIM HR/SpO2 IC would receive raw data from blood vessels and stores it as raw data. an MPU would interface with it, processes the raw data, and display it on an LCD, and send it to a Bluetooth module to be displayed on a smartphone.

Measure your heartbeat using your phone's camera and flashlight, based on the principle of photoplethysmography

a sample demo for Berry Medical's Oximeter which have Bluetooth Low Energy inside.
