For people who exercise regularly, the smart bracelet should be a very familiar technology product. The sports smart bracelet is not simply to look at the time, it is as simple as reading the stopwatch, it has other high-tech functions , The motion monitoring function is realized by the gravity acceleration sensor.

The sensor obtains some basic data by judging the movement of the person, combined with the basic information of the personal physical signs input by the user before, and according to some specific algorithms, obtains personalized monitoring data for individuals, such as exercise steps, distance, and calories burned. To determine the frequency and intensity of the exercise.

For these transmission functions, what is the mystery in the sports smart bracelet? What components does it use to achieve its function?

After long-term cooperation with manufacturers specializing in the production of sports smart bracelets, it is concluded that the Everlight electronic model series used in sports smart bracelets cannot be separated from infrared emitting tubes, infrared receiving tubes, light sensors, and SMD LEDs. So what are their specific models?

The heart rate sensor of the sports smart bracelet and the blood oxygen sensor are mainly used in the special infrared transmitter IRR60-48, IRR15-22CL/L491 of the oximeter.

In the ambient light sensor, Everlight ALS-PD70-01C is applied. In signal reception, it is recommended to use infrared receiver tube PD60-48C or Pd15-22C. In the indicator screen of the sports bracelet, it is recommended to use Everlight's 67-21/GHC-BV1 and 15-21/GHC-R2S2 patch lights.
