About This Project

The green light behind the Apple Watch is the primary sensor that measures heart rate. This light is emitted by the device and reflected back by a number of sensors. The sensors can measure the amount of red blood cells in your blood and calculate your heart rate. You can turn this feature off by pressing and holding the side button until the Apple logo appears on the screen. click here: green light behind apple watch
