Sports smart bracelet function
Record sports data
Smart bracelets can record various sports data, including steps, distance, calorie consumption and other data, but it does not distinguish between different types of sports. Caliba is only about value.
Sports smart bracelets can also monitor heart rate and body temperature. Use reflective photoelectric sensors to collect photoelectric signals to monitor the changes in calculating blood capacity, and then calculate the basic parameters of the human heart rate based on the inhalation of the material in the blood and the concentration of the material in the blood. Body temperature detection is to convert temperature changes to changes in the resistance value with thermistor, then use the corresponding measurement circuit to convert the resistance value to voltage, then convert the voltage value to digital signals, and then processes the digital signals accordingly. Temperature value.
Record sleep data
Through contact with the wrist, the sensor monitors the movement, heart rate status, and body movement frequency, and calculate the sleep status and energy consumption of the subject’s sleep, and the algorithms of different products are different. The smart bracelet clearly records four information such as sleeping time, deep sleep time, shallow sleep time, and awakening time.
Alarm clock function
If you have the need to record sleep, the alarm function is very practical. The way he wakes up is not as simple and rude as the traditional alarm clock, but a vibration method, so that the wake -up rate is high and will not affect others.

The smart bracelet has a waterproof function. You can wear a shallow sea or a river swimming with a hand ring within 10 meters. It overcomes the defects that the traditional paceer cannot track swimming, and it is more widely used.
Smart bracelet working principle
Intelligent bracelet step counting principle
The core component of the step counting function is the acceleration sensor. The acceleration sensor can perceive the direction and acceleration of the object movement. Collect the amplification and filter circuit.
Smart bracelet heart rate monitoring principle
Use reflective photoelectric sensors to enter the deep tissue through the skin through the skin, except for being absorbed by the skin, muscles, blood, etc., the remaining part of the light transmission is perceived by the optical receiver. The changes in blood and the periodic changes of blood volume constitute all the basis for the use of PPG signals to perform heart rate estimation. By calculating the distance between the characteristic points (such as peaks) within the adjacent cycle, the heart rate estimation is achieved.
Smart bracelet sleep monitoring principle
The sensor of the smart bracelet measures the quality of sleep based on the amplitude and frequency of the wrist; the body movement recorder detects small motion by detecting, and determines that the sleep state is sober, light sleep or deep sleep.
How to use smart bracelets
Installation and disassembly of the host
The installation of the host refers to fixing the host to the wristband to facilitate the wearing of users. Its operation method is very simple. You only need to insert the USB on the host to the corresponding interface of the wristband and fix it by pressing the lock. If you want to remove the host, you should first bend the wristband to the lower below to make the host pop up, and then take out the host.
How to connect to the mobile phone in the smart bracelet
First download and install and open the app on the mobile phone and open it; then turn on the mobile phone Bluetooth, call the main menu on the APP homepage, and click the device to bind. Then light up the bracelet, click “Search”, the device name of the bracelet is displayed in the equipment list, and click the device name; finally, the prompt device will be successfully binding and the Bluetooth pairing request, and click “OK” and “Match”, the bracelet, the bracelet, the bracelet, It is bound to the phone.
Smart bracelet function use
1. Objective settings: Enter “target settings” from the main menu, set the number of target steps daily, and the number of steps to reach the target step of the bracelet will vibrate reminds.
2. Sleep monitoring: Set up the sleep time period from entering “Sleep Settings” from the main menu, to the time of the time, the bracelet will vibrate into the sleep mode and start monitoring sleep. By the time of the wake up, the bracelet will exit the sleep mode by itself. The mobile phone can see sleep data in Zero 1.
3. Sitting reminder: Enter the APP to open a sedentary reminder, and set the time period that takes a sedentary reminder. The reminder cycle per hour, as long as the number of activities in half an hour does not reach 200 steps, the smart bracelet will vibrate to remind.
4. Alarm clock settings: Enter “Alarm Clock Settings”-“Add Alarm” set up the corresponding time point to select the date that needs to be repeated.
How to adjust time
1. The time adjustment of most exercise bracelets is on the front, there are two very small keys, and the fingers can modify the time.
2. There is a kind of sports bracelet setting time to stick the arm on the back of the bracelet. This bracelet setting key is very small. You need to use a pointed thing like a pen to be used as a tool to set it.
