Is it possible to plot in real time the plethysmography graph with SEN-15219?

Good morning everyone!

I am currently using the SEN-15219 to measure heart rate and SpO2 with Arduino. While it is super useful to have the output as the final calculation of the BPMs and oxygen, I was wondering if it is possible to extract the raw data of the sensor (as to be able to plot in real time the plethysmography graph… or alternatively, store each sample and plot the curve afterwards). The reason behind it, is that I would like to visualize and possibly store this curve for further analysis.

I would like to know if anyone has tried and succeeded on this.

There’s a serial plotter function in the Arduino IDE that might work for you.

Study the MAX32664 Sensor Hub User Guide to learn how to access the raw sensor data.
