How to use the Heart Pulse Detector
- Place your finger on the camera and make the entire camera screen red.
- This application uses the phenomenon that the color of the finger periodically changes according to the blood flow.
- Please press it lightly. If you press hard with your finger, blood will not flow and it would be hard to measure.
- Do not move as much as possible to stabilize the blood color graph.
Pulse represents the number of heartbeats per minute, which can be assessed by palpating an artery against a bone.
