Continuous heart rate monitoring works by using a sensor to detect the electrical signals produced by the heart as it beats. This sensor is typically embedded in a wearable device such as a smartwatch or fitness tracker. The sensor continuously measures these electrical signals and converts them into a digital signal that can be analyzed to determine the user's heart rate. This information is then displayed on the device's screen or transmitted to a connected app for further analysis and tracking. **
