AN INFRARED PHOTOSENSITIVE SENSOR. CONSISTS OF A MONOLITHIC HYBRID INTEGRATED CIRCUIT. THE DEVICE IS DESIGNED TO BE USED AS A COMPONENT IN A PEOPLE COUNTING APPARATUS. IT DETECTS THE CHANGE IN DIFFERENT LEVELS OF THERMAL ENERGY FROM A SCENE, AND CONVERTS IT INTO DIFFERENT ELECTRICAL SIGNALS. THE VALUE OF THESE ELECTRICAL SIGNALS, WITH 61 X 80 ELEMENTS/PIXELS. REPRESENTS LEVELS ACROSS THE SCENE IN VIEW. THE OUTPUT OF THE DEVICE IS THEN USED TO MONITOR THE CHANGE IN THERMAL SCENE AND THE MOVEMENT OF OBJECTS THAT ARE AT A DIFFERENT TEMPERATURE FROM THE BACKGROUND, EITHER HOTTER OR COLDER. DIMENSIONS 36 X 31 X 9 MM.
