The principle of heart rate measurement on the wrist is simple:
Light is irradiated onto the skin and an optical sensor measures the reflection of the light. How much light is reflected is influenced, among other things, by how much blood passes through the illuminated spot. The blood flow changes during the beat of the heart. The heart rate is recorded in this way.
The iD.LIFE gives discreet feedback via the vibration alarm, for example, if a day's target has been achieved and it also helps to monitor the target heart rate better.
This is an important feature particularly in a noisy environment.
The iD.LIFE uses a 3D accelerometer. By recognising the striking patterns of movement, steps can be detected and recorded.
The distance is measured using this motion sensor. To adjust the measurement accuracy to your own running style, you can calibrate the iD.LIFE, for example, on the track at a stadium.
