The Micropower Hall Sensor is a magnetic field sensor fabricated according to the Hall effect. The Hall Effect IC is a kind of magneto electric effect. This phenomenon was discovered when the cattle named Hall were studying the conductive mechanism of metal in 1879.
Its role in the mobile phone is the Hall Switch, which can make our mobile phone case smart. The specific effect is to open the bright screen and close the black screen. This feature is often used in flip phones, and of course on tablets.
In short, if the mobile phone with a Hall sensor, as long as a magnet is built in the holster, the above functions can be achieved, and most of the smart machines currently have Hall sensors.
