Fitness trackers, also known as activity trackers, employ a combination of sensors and technology to monitor and record various aspects of an individual's physical activity and health. These compact devices 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 and route information during outdoor activities.

Sleep tracking is another common feature, utilizing accelerometer data and sometimes additional sensors to analyze movement patterns and provide insights into the quality and duration of sleep.

The collected data is typically synced with a dedicated mobile app or computer software, allowing users to review their activity trends, set goals, and gain a comprehensive understanding of their fitness levels. This combination of sensors and user-friendly interfaces empowers individuals to make informed decisions about their health and wellness based on real-time data and historical trends.
