Embodiment Construction

[0059] like figure 1 As shown, the anti-myopia reminder device of the present invention faces the user's head when the reminder device is in use. The device includes a single-chip microcomputer, a master steering gear and a slave steering gear. Control the first laser ranging module to swing up and down to locate the top of the user's head and eyes, measure the distance between the user's eyes and the book, and control the second laser ranging module to swing left and right from the servo connection to locate the user's The position of the whole head, measuring whether the user is tilting the head or not.

[0060] The single-chip microcomputer is also connected with the photosensitive sensor module and the active buzzer. The microcontroller is also connected to a Bluetooth module. The device uses an Arduino nano board as the mainboard of the microcontroller.

[0061] in:

[0062] ●Arduino nano board: all measured and calculated data are returned to the microcontroller
