Accelerometers and GPS are standard components which can also be seen in a smartphones.

Accelerometers allow the Fitness tracker to tell how many steps you’re taking everyday. Whereas GPS, track total distance walked or ran by you.

But unlike your smartphone some good fitness trackers have more advanced motion sensors. These motion sensors are not only more accurate but can use positional data to determine exactly what exercise you’re doing.

Heart rate tracking

Unlike the EKG which your doctor uses to monitor your heart rate, the fitness tracker enabled with an optical heart-rate, measure your heart rate using light. This is to figure out how good your heart is working.  They shine light at your skin that’s powerful enough to light up your capillaries to figure out how much blood is flowing based on how much light is reflected back.  Capillaries are the little blood vessels close to the skin’s surface.

Higher-end models even measure your skin’s electrical impedance which fluctuates based on how fast your heart beats. This is the same tech used in heart rate monitors on gym treadmills

UV sensors

UV sensors in your fitness band informs you, while you are absorbing harmful UV radiation from the sun. The related software warns you to get out of the sun by comparing the UV radiation values around you, with the values identified by the scientists, to be harmful. Thereby protecting you from the sun if you are likely to burn.
