# MAX30100 SPO2 and Heart Rate Sensor

The MAX30100 is an integrated pulse oximetry and heart- rate monitor sensor solution. It combines two LEDs, a photodetector, optimized optics, and low-noise circuitry.

We will read and plot values from both photosignals and observe the heart rate

Place a finger over the MAX30100 chip, and observe that once the program starts executing, the RED LED turns on. The graph will show heart beats. 

## Further

The Infrared LED is not visible to the human eye, but if you look at it through your phone's camera, it will appear in a purple colour. Magic.
