Abstract
A pyroelectric infrared sensor includes light receiving electrodes and light reflecting electrodes being arranged in a two-set-three-series relative to top and bottom surfaces of the pyroelectric material. The first through sixth light receiving electrodes are formed to be of opposite polarity to each other. The first through sixth reflecting electrodes corresponding to the first through sixth light receiving electrodes are formed on the bottom surface of the material and connected to the connecting electrode of the same polarity so that a sensed signal of the same magnitude of infrared rays having the same energy irrespective of direction is outputted.
