Q:Why is the blood pressure value deviated from the sphygmomanometer?

A:The deviation between the measurement value of the watch and the sphygmomanometer is determined by a variety of factors. The measurement site of the sphygmomanometer is in the radial artery, and the measurement site of the watch is the two main branches of the arteriole. Normaly, the aortic blood pressure measurement and the arteriole Blood pressure measurements will vary by three to forty; if you use a watch and a sphygmomanometer to measure at the same time, because the blood flows in the artery in the direction of the centrifuge, the sphygmomanometer measures the straps so that the lower part of your elbow is under pressure. Temporary blood cannot flow smoothly to the branch of the artery below, and the vascular tension is increased, which will make the upper and lower blood pressure measurement values more biased.

Q:Why can't the watch receive the message push?

A:Android phone settings1. Confirm that the message push switch is enabled on the mobile client.2. The confirmation message can be displayed normally in the mobile phone notification bar. The watch message push is pushed by reading the mobile phone notification bar message; if there is no message in the mobile phone notification bar, the watch will not be able to receive the push(need to find the notification setting in the phone settings, open WeChat, QQ phone, SMS, notification button of mobile client)3. Open the auxiliary function settings of the wristband client(see the auxiliary function in the settings on the phone, and open the auxiliary function settings of the wristband client)

Apple phone settings:1. Confirm that the message push switch is enabled on the mobile client.2. the confirmation message can be displayed normally in the mobile phone notification bar(need to find the notification settings in the phone settings, open WeChat, QQ phone, SMS, mobile phone client notification switch)

Q:Why does the pedometer not count steps when I have already started walking?

A:To reduce errors, smart watch usually sets an initial value of 10, it will count steps when we walk more than 10 steps. The APP will show the real walking steps and start counting from step 10.

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
