The body sensing and air direction controlling apparatus comprises a fan motor controller for rotating a fan connected to a fan motor by the control of a microprocessor, a air direction left/right controller for controlling air direction, an infrared sensor module for sensing an infrared ray from the body, a Fresnel lens for sensing the position of the body, and a body position sensing circuit for amplifying and filtering the output signal of the Fresnel lens, thereby sending the air direction toward the user.
