Heart rate detection function

Heart rate is a problem that needs to be paid attention to in people's normal exercise. Smart bands can help people measure heart rate. They are in contact with skin. The method is the photoelectric transmission measurement method. It uses the contact between the intelligent band and the skin. It hits a beam of light on the skin, allowing the light wave to penetrate the blood and refract back. Blood absorbs light of a specific wavelength. This wavelength will be absorbed in large quantities every time the heart pumps blood. The detected heart rate is not accurate. But it is sufficient for detecting the change of heart rate during human exercise.
Sleep monitoring:
The electronic sensor of the intelligent band can detect the human movement and heart rate by touching the skin. Some people sleep lightly when they sleep. Their heartbeat will accelerate when they dream. Their heartbeat will be smooth when they sleep smoothly. It can help people perceive their sleep state and make targeted adjustments. It can play an auxiliary role to a certain extent.
