First of all, different sleep monitoring products are very different in principle. This mainly involves receiving the influence of the product hardware. Polysomnography is a medical device that monitors a variety of data during sleep, such as rolling over, breathing rate, eye movement, brain waves, heart rate and other data. Through these data to determine the patient's sleep condition and possible diseases. So that doctors can treat the symptoms.
Polysomnography equipment is more specialized, but as medical equipment is not likely to enter the home. The general public does have the need to understand the sleep condition and improve sleep in their daily life. As a result, many sleep monitoring devices have emerged, and the principles vary from device to device.
Let's talk about the most common bracelet, in fact, bracelet sleep monitoring has been criticized by many users, because its monitoring is really inadequate. There is no way to monitor a number of data like a medical device, but at most it detects the movement of the wrist to simply determine whether the user is asleep, and a large error is inevitable.
There is also software that uses cell phones directly, roughly using the accelerometer sensor inside the phone to monitor the user's frequency of activity during sleep, but again, the monitoring data is too single and the judgment is inaccurate. There are also devices that monitor through radio frequency, which can be used to determine the body movement during sleep. Again, the monitoring data is single and there is also the problem of radiation. In winter, the blanket is too thick and may not be accurate.
How to use the sleep monitor correctly
1, place the sleep monitor under the bed sheet, close to the chest heart position, put stable and spread the bed sheet, the magnetic suction top cover across the bed sheet adsorption on the host.
2, press the host button, the blue light blinks on behalf of the host is working properly, the power is sufficient. If you press the host button red light flashes twice in a row, indicating that the host power is low, need to charge. If you press the button no response, it means that the host is completely out of power, you need a long time to charge to activate the device. The red light blinks in the charging state, and the red light stays on after fully charged.
3, download APP installation, registration, open the cell phone Bluetooth, pairing connection host device.
4, open the "monitoring" page, click on the open button, view real-time respiration, heartbeat waveforms and values, view the bed and out of bed corresponding to the APP display status, when you do not need to monitor click on the close button.
