Information

Although there are many sports watches on the market, they can still be classified. Generally speaking, according to the type of motion sensor, it can be divided into the following three categories: pedometer sports watch, GPS sports watch and heart rate sports watch.
1. Pedometer sports watch
The motion sensor of the pedometer sports watch is a 3D acceleration sensor, which can sense the three-dimensional motion acceleration generated by the human body, so as to record the number of steps per unit time, and then calculate the speed, distance and weight of the human body through the input step length. This is used to calculate the calories burned by individual exercise.

2. GPS sports watch
The GPS sports watch determines the track point by receiving the satellite position signal, and calculates the distance moved per unit time, so as to calculate the moving speed. The accuracy of the position signal will be determined by the strength of the satellite signal and the sampling rate. If you are outdoors, the signal is more susceptible to interference from environmental factors such as weather.
3. Heart rate sports watch
The heart rate sports watch is to measure the heart rate of the human body by sensing the cardiac current of the human body. Heart rate sports watches can be divided into two categories: heart rate sports watches with chest straps and heart rate sports watches without chest straps (photoelectric heart rate sports watches).
