Heart Rate Measurement Principle Explanation:
We use optical PRG technology to detect heart rate. When your heart beats, blood flows in and out of the capillaries in your fingertips, causing subtle tissue color changes. The phone’s flash illuminates your fingertip, and the camera captures these changes to analyze your heartbeat frequency.
