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.

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

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

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.

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

Measure your heartbeat just by using your phone camera and flashlight, with the basic concept of Photoplethysmogram.

Wearable Continuous Pulse Oximeter based on PPG(Photoplethysmography)

Pulse oximeter using Arduino to read and display heart rate and oxygen saturation levels in real-time

demo for classic bluetooth.

A novel IoT Pulse Oximeter to cope with COVID-19 pandemic

In this project, I have utilized the Bluetooth communication protocols of Berry med (with and without ECG) to transfer the heart rate, SpO2, and their waveforms to the webpage directly from Bluetooth, such a method can be used to directly upload the data to the database.
