At the same time, a mini body fat scale in 99 yuan and a millet body fat scale in 199 yuan were dismantled, and it was found that millet used a plane sensor, while the product body fat scale used a point sensor. As we all know in the industry, the accuracy of point sensor is higher than that of area sensor, and the cost of point sensor is higher.
2. Because the area sensor is used, the scale foot of Xiaomi must be fixed, so as to ensure the stability of the upper and lower stress points. However, because of the point sensor, the foot of the high-quality body fat scale is a movable "universal" foot. The difference between them is that when there is a slight horizontal difference in the ground, the universal foot can better filter out the measurement error caused by the inclination of the scale surface.
3. The electrode plate area of millet body fat scale is relatively small, and the circle is relatively regular. In contrast, the electrode plate of millet body fat scale is larger, oval and X-shaped, allowing users to stand in a wider range for effective contact.
4. The millet body fat scale is made of ABS plastic, and the product body fat scale is made of tempered glass. The deformation of plastic is usually larger than that of glass, which brings about the difference of measurement accuracy. In addition, the glass is easier to clean, but the disadvantage is that the scale is a little cold in winter.
5. Preventing rollover is the basic requirement to ensure the safety of measurement. By visually comparing the rollover angle, we can see that the rollover angle of Xiaomi is relatively large.
6. In order to smooth the data, Xiaomi is suspected of using a memory-weighted algorithm, that is, when the perceived weight is not much different from the last time, the previous data is automatically adopted. Every time the product is weighed again, you can feel the slight difference. You can use your mobile phone as a weight and weigh it as a comparison.
