Interfacing max30100 pulse oximeter sensor with arduino.
Blood oxygen sensor arduino.
Optical reflection signal ppg output signal interface.
I2c bus pull up level you can choose 1.
The blood oxygen concentration termed as spo2 is measured in percentage and heart beat pulse rate is measured in bpm.
Since i have a ky 039 sensor i ve decided to modify it.
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.
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.
As a builder of gadgets and a scuba diver i have been trying to build an oxygen analyzer for a bit now.
The obvious conclusion is that led1 is ir and led2 is red i e.
Swapped which also works when computing blood oxygen see below.
Easy to build oxygen analyzer using an arduino compatible micro controller.
Heart rate sensor module max30102 blood oxygen sensor compatible with arduino stm32 parameters.
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.
Makerfocus heart rate sensor module max30102 blood oxygen sensor compatible with arduino stm32.
1 8 5v interface.
The blood oxygen concentration termed as spo2 is measured in percentage and heart beat pulse rate is measured in bpm.
I played with opamps but never got it to work properl.
4 2 out of 5 stars 33.
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.
660nm 880nm led power supply voltage.
In this project we will make a device that can measure blood oxygen heart rate using max30100 pulse oximeter arduino.
