Main power input 1 8v 2 5v 3 bit pad.
Blood oxygen sensor arduino.
The obvious conclusion is that led1 is ir and led2 is red i e.
Swapped which also works when computing blood oxygen see below.
Interfacing max30100 pulse oximeter sensor with arduino.
Heart rate sensor module max30102 blood oxygen sensor compatible with arduino stm32 parameters.
As a builder of gadgets and a scuba diver i have been trying to build an oxygen analyzer for a bit now.

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.
The blood oxygen concentration termed as spo2 is measured in percentage and heart beat pulse rate is measured in bpm.
Get it as soon as thu sep 17.
4 2 out of 5 stars 33.
I played with opamps but never got it to work properl.
Makerfocus heart rate sensor module max30102 blood oxygen sensor compatible with arduino stm32.
The big problem is that most micro controllers can t read the mv that the sensor puts out.
That value is called sp02 peripheral capillary oxygen saturation.

In this project we will make a device that can measure blood oxygen heart rate using max30100 pulse oximeter arduino.
I2c bus pull up level you can choose 1.
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.
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.
The blood oxygen concentration termed as spo2 is measured in percentage and heart beat pulse rate is measured in bpm.
3 3 5v detection signal type.
Optical reflection signal ppg output signal interface.
Since i have a ky 039 sensor i ve decided to modify it.
660nm 880nm led power supply voltage.
1 8 5v interface.
The max30100 is a pulse oximetry and heart rate monitor sensor solution.
