Abstract
The present invention relates to a device for sensing the position of a human body using an infrared ray sensor including: a light focusing device for converging an infrared ray emitted from the human body; a guiding device for guiding only a predetermined direction infrared ray among the infrared rays converged by the light focusing device; an infrared ray sensing device for sensing the infrared ray received by the guiding device; a direction shifting device for shifting the sensing direction of the infrared ray sensing part up, down, right and left; a circuit device for amplifying the output of the infrared ray sensing device, A/D converting it and then driving the direction shifting device; and a determination device for determining the position, movement direction and the activity of a human body using an output signal of the circuit device and a driving timing of the direction shifting device.
