Heart Rate Sensor

How It Works

The heart rate sensor in the iWatch Series 11 uses advanced optical technology. Small lights on the back of the watch shine onto the skin. The sensor measures how much light bounces back. Blood absorbs light differently as it moves through the wrist. The sensor detects these changes and counts each heartbeat. This process gives a real-time reading of the user’s pulse.

The iWatch Series 11 checks the heart rate all day. It works during exercise, rest, and sleep. The sensor can also take spot checks when the user wants to know their pulse. The watch stores this data and shows trends over time. The heart rate sensor works well with other sensors, such as the accelerometer and gyroscope. These sensors help the watch know when the user is active or still. The watch uses this information to give more accurate readings.

Tip: Users can view their heart rate data in the Health app. The app shows daily, weekly, and monthly trends.

Health Benefits

Heart rate monitoring helps users understand their health. The iWatch Series 11 alerts users if their heart rate goes too high or too low. These alerts can help users notice problems early.
