Hi,
I would like to visualize the respiration levels in the chest and abdominal area.
For that reason i'm using an Arduino and a piezo electric sensor.
Since the sensor has its own connector, i did some extra wiring(described in the attached picture).
I'm currenly just testing the abdominal area.
I see that the variations of the signal are not big enough so that you can tell someone is actually breathing.
The idea is to test the patterns, so that eventually new patterns can guide the user for better respiration techniques.

I include the graph that it get when there's no breathing (i wish it could be as flat as possible in that scenario).
I think for testing this signals something that streches should do the trick.
I appreciate your help if there's another one that works better for this purpose.
Regards,
