How does the Heart Rate Monitor Work in a Fitness Tracker?

Activity Trackers describe their heart rate technology as having the optical sensors on the underside. When your heart pumps, your capillaries grow and shrink based on blood volume differences. In turn, the LED lights on the device reflect onto the skin to detect blood volume variance, with algorithms processing these in order to try and accurately measure the beats per minute.
