I have the AD8232 EKG sensor and have followed the tutorials on spark fun and such to see a visual of my heart rate. This has worked, but I would like to find a way to get a ## from the sensor, such as 80 bpm, but have no idea how to interpret the numbers the sensor spits out.
Thanks
Most likely, you will read the sensor output using analogIn() and then use a peak detection algorithm to identify and time the appropriate repetitive peaks. You will probably have to implement data smoothing/noise reduction as well.
Considering sensor and environmental noise, this is not at all a simple task, but surely examples have been posted on the web.
