Smartwatch

In recent years, smart watches have been used in electronic devices that are worn on the body and are used for various purposes. A smartwatch is a small computer with an LCD screen and is attached to the wrist instead of a wristwatch. Many are connected to other electronic devices such as smartphones, and some are equipped with accelerometers and GPS functions inside, and a sensor for heart rate measurement on the back side.
In addition to the original wristwatch function, it also has functions such as health management using a pedometer and heart rate meter, notification function in cooperation with smartphones, electronic money payment function, music playback, photography support, voice operation and recording.
The sleep meter function of a smart watch uses an accelerometer to detect the direction of the body and turnover, which measures sleep time and sleep quality (lem sleep, non-lem sleep), and some of them improve accuracy by adding heart rate meter data. The sleep meter function allows you to see the amount and quality of your sleep.
