These compact [devices](https://www.mindstick.com/news/2581/android-and-google-nest-devices-can-now-communicate-with-matter) typically incorporate accelerometers, which detect motion and measure the intensity and duration of activities like walking, running, or cycling. The accelerometer provides data on steps taken, distance traveled, and even the number of floors climbed.

Additionally, many fitness trackers include heart rate monitors, often using optical sensors to measure the user's pulse through the skin. This heart rate data offers insights into exercise intensity and overall cardiovascular health. Some advanced models may also incorporate GPS technology to track precise [location](https://www.mindstick.com/news/2574/twitter-conveniently-reveals-a-location-sharing-policy-amid-elonjet-controversy) and route information during outdoor activities.
