Blood oxygen sensor arduino.
I2c interface communication interface voltage.
Easy to build oxygen analyzer using an arduino compatible micro controller.
The big problem is that most micro controllers can t read the mv that the sensor puts out.
I played with opamps but never got it to work properl.
In this project we will make a device that can measure blood oxygen heart rate using max30100 pulse oximeter arduino.
The max30100 is a pulse oximetry and heart rate monitor sensor solution.
The red light 600nm is absorbed better by the blood that contains more oxygen so we can compare the measures made with infrared led 950nm with the ones made with red led and find the percentage of oxygen in our blood.
Makerfocus heart rate sensor module max30102 blood oxygen sensor compatible with arduino stm32.
The blood oxygen concentration termed as spo2 is measured in percentage and heart beat pulse rate is measured in bpm.
The blood oxygen concentration termed as spo2 is measured in percentage and heart beat pulse rate is measured in bpm.
Optical reflection signal ppg output signal interface.

The obvious conclusion is that led1 is ir and led2 is red i e.
660nm 880nm led power supply voltage.
Swapped which also works when computing blood oxygen see below.
3 3 5v detection signal type.
Main power input 1 8v 2 5v 3 bit pad.
In this project we will be interfacing max30100 pulse oximeter sensor with arduino that can measure blood oxygen heart rate and display it on 16x2 lcd display.
Max30100 pulse oximeter arduino in this tutorial you will learn how to use the max30100 pulse oximeter with arduino and display the heart rate and blood oxygen on a 16 2 lcd the heart rate or pulse rate or heart beat is measured in bpm which is also known as the beats per minute while the blood oxygen concentration is measured in percentage.
I mention this as the most common driver used in arduino projects for the max30102 is the sparkfun 3010x driver which clearly identifies led1 with red and led2 with ir.
1 8 5v interface.
I2c bus pull up level you can choose 1.
Interfacing max30100 pulse oximeter sensor with arduino.
That value is called sp02 peripheral capillary oxygen saturation.
As a builder of gadgets and a scuba diver i have been trying to build an oxygen analyzer for a bit now.
