Hello, everyone. The meeting will answer your questions. Wechat 20, 000 steps about how many kilometers, Wechat 20, 000 steps is how many kilometers, many people do not know, now let's take a look at it!

Answer:

1. Wechat 20, 000 steps is about 11 kilometers; Wechat uses mobile phone hardware to measure the pace, so we can first understand the principle of the pedometer. Whether Wechat or other software with pedometer function, it is actually realized through the gyroscope, gravity sensor and intelligent pedometer module inside the phone. According to statistics, the normal stride of a man with a height of 175-180CM is 45-65CM from the toe of the hind foot to the heel of the forefoot.

2. About gyroscopes:

3. The main function of gyroscope is to judge the motion and vibration of space. When walking or running, the mobile phone will swing back and forth with the movement, forming spatial displacement and vibration. The gyroscope can record the number of vibrations and movements and output them to the intelligent pedometer module.

4. About gravity sensors:

5. It can be seen from the above that gyroscopes can accurately record footsteps when moving on flat ground, while gravity sensors can help us accurately record the footsteps of non-flat ground movements, such as climbing stairs, jumping or running.

6. Intelligent pedometer module:

7. The intelligent pedometer module is also a very important part; it will process and judge the output data of gyroscope and gravity sensor, and finally get the approximate number of steps per day.

This is the end of this article. I hope it will be helpful to all of you.
