Why is my Fitbit not showing my heart rate?
One of the useful features of the Fitbit Charge 5 is that is can measure your heart rate. The technology used to do this is called photoplethysmography. The light sensitive photodiodes at the back of the watch acts as the optical heart rate monitor. This green light blinks many times per second when your heart rate is being measured. The higher your blood volume is, the more green light is absorbed. And the lower your blood volume, the less green light is absorbed.
