The watch has a built-in acceleration sensor. The data is detected by the acceleration sensor and then combined with the algorithm and the basic information of the human body, and finally the information is displayed as the number of steps, calorie consumption and other information.
The reasons for the inaccurate data of the Redmi Watch 5 Lite are listed below:
1. The principle of measuring the walking distance of a watch is to estimate the step length according to your height, sex and weight, and then multiply it by the number of steps taken by you to obtain an estimated value;
2. Because the mileage varies, and people of the same height, sex and weight also have different steps, the final calculated value will also have large deviations;
3. The accuracy of step counted, that is, the number of steps taken, also has many uncertain factors that will have a great relationship with everyone's behavior habits, such as the amplitude of arm waving, walking habits, etc. There are many scenes of human activities (such as walking, riding, driving, bathing, etc.), and arm movements are more complicated (such as keyboard tapping, moving the mouse, lifting and pulling objects, etc.);
4. It is because of the above reasons that the final calculated distance of the watch is also an estimated value. The watch cannot be used as a professional measurement tool to measure the distance. We will continue to optimize the software algorithm to calculate more accurate data.
