LASIKA SPORT WATCH supplier believes that sports watches can be divided into three categories according to the type of their motion sensors: pedometer watches, GPS watches, heart rate watches. Of course, there are many types of non-professional sports watches.

pedometer watch
The motion sensor of the pedometer watch is a 3D acceleration sensor, which can sense the three-dimensional motion acceleration generated by human movement, such as walking and running, so as to record the number of steps per unit time. Calculate the movement speed and distance of the human body through the input step length, and calculate the consumed calories through the input weight.
GPS watch
GPS watches calculate the distance moved per unit time by receiving satellite position signals, and estimate the speed of movement. The accuracy of the position signal is determined by the strength of the satellite signal and the sampling rate. The advantage is that the trajectory of the movement can be recorded and synchronized to the map.
heart rate watch
The heart rate watch is to measure the heart rate of the human body by sensing the cardiac current of the human body. The heart rate of the human body varies with different exercise intensities. Selecting different heart rate zones can achieve different training exercise effects.
