Digital sport watches The motion sensor is a 3D accelerometer that senses the three-dimensional motion acceleration digital sport watches generated by a human body when walking, such as walking, so that the number of steps per unit time can be recorded. The movement speed and distance of the human body are calculated by the input step size, and the calories burned are estimated by the input weight. The advantage is that it can be used for outdoor indoor sports, weather-proof and very power-saving, and can store motion data for a few days. The digital sport watches calculate the distance moved per unit time by accepting the satellite position signal WAYPOINT and estimate the speed of the movement. The accuracy of the position signal is determined by the strength of the satellite signal and the sampling rate. For example, the accuracy of the 1-second sampling rate is obviously higher than the 60-second sampling rate. However, too high a sampling rate can cause the battery to drain too quickly. The advantage is that the trajectory of the movement can be recorded and synchronized to the map. The digital sport watches measure the heart rate of the trendy digital watches human body by sensing the heart current of the human body. The human body has different heart rate at different exercise intensity. The international percentage of the digital mens wrist watches heart rate of the exercise heart rate is divided into light activities: 50-60%, aerobic exercise 60-75%, endurance training 75-85%, intensity Training 85%-100%. Different training heart rate areas can achieve different training effects.
