Lerbyee Fitness Tracker K1 Smart Bracelet Real-time Heart Rate Monitor Smart Watch Activity Tracker for sport iOS Android

The order was issued on april 11, 26 already took from the post office in Izhevsk. The track was tracked without problems. I ordered two bracelets, one for my mother, the second for myself. While i tuned only my own, it seems that everything functions. As it notifies about incoming calls and sms i do not know yet. On the display protective film, the screen is completely touch, there are no buttons. A good reliable strap (before lost the fitness tracker, the strap unfastened). The seller chose on the recommendation of a friend, actually i advise you.

The order came quickly. There was no spare bracelet. The app downloaded qr code on the box. Annex in russian. Everything is clear and simple. Let's see what happens next

The goods are cool. Fully corresponds to the description. Quickly set up, everything is clear. Thanks to the seller. The clock came charged at 40%.

Thank you very good service

Great product, as the description, satisfied with the purchase, Bought again another different color product

For the problem that the bracelet can measure the heart rate in things and in the air, the following explanation is made:

1.At present, the mainstream heart rate bracelets on the market adopt the same measurement method. The principle is not complicated, that is, the PMG signal of the radial artery is obtained by the reflective photoelectric measurement method, and the fast Fourier transform is performed on the PPG signal to analyze the frequency domain. To achieve the detection of the human heart rate. To put it simply, it is to use a light to the artery and then reflect it back. Based on the change of the reflected light, the heart rate of the human body is calculated.

2.Due to many factors such as the physiological structure of the human body, the color of muscles and blood, green light is the color with the highest passing rate in the human body. Therefore, the light source of the heart rate sensor uses green light to achieve minimum loss and interference.

3.Heart rate wristband detection focuses on human tissue. Some data is also read for non-human objects. This is a known and normal phenomenon. After the data is based on the principle of light reflection, the heart rate detection will have a reading. This situation cannot be All avoided, so there will be problems with heart rate data in the case of heart rate bracelet (table) in the case of "air test".
