Control apparatus for controlling IoT devices with rotation operation

A controller apparatus for controlling IoT devices, comprising:

• a rotation disk having a rotating shaft in an inner surface of the rotation disk for generating a rotation operation, the rotation operation being either a clockwise rotation or a counterclockwise rotation;
• a rotation detection circuit for detecting the rotation operation of the rotating shaft, the rotation shaft is adjustable to fit a plurality of vertical positions;
• a control circuit for retrieving the rotation operation from the rotation detection circuit, and generating a control instruction according to the rotation operation, and when one vertical position is chosen by a user, a second control instruction is generated for controlling a corresponding external device;
• a wireless circuit for transmitting the control instructions to the corresponding external device to control the corresponding external device;
• a circuit board for mounting the wireless circuit and control circuit;
• a motion sensor for converting a user motion applying on the controller apparatus to a third control instruction to control the corresponding external device;
• and
• a housing, wherein one end of the rotating shaft is connected to the inner surface of the rotation disk and the other end of the rotation shaft is connected to an inner part of the housing, and the rotation detection circuit and a circuit board circuit are disposed in the housing, wherein the rotation disk and the housing have circular shapes, and the rotation disk and the housing together form a circular disk device with a size to be carried with a hand of a user.
