Why is there a delay in turning the wristscreen?

Because of the power consumption considerations, there is no frequent reading of the acceleration sensor data, and a fixed time interval is set, so if the moment of turning the wrist just happens to be stuck in the interval, there will be a feeling of delay.

What principle does the bracelet measure heart rate?

Photoelectric volume pulse wave tracing: referred to as PPG, the blood is red, reflecting red light, absorbing green light. When the heart beats, the blood flow increases and the amount of green light is absorbed. The receiver reflects the number of heartbeats based on the intensity of the received light.
