Is anyone working on the use of the Raspberry Pi Camera module as a heart rate sensor?
I am new to using Raspberry Pi. I want to build a non-contact real-time heart rate monitoring system using Raspberry Pi 3 Model B and Pi NoIR camera.

The wand will have the transmitter.
The ball will have the receiver in it.
I want to make it stop when the wand is...
