Abstract

MODIFICACIONES EN DETECTORES DE INTRUSION INFRARROJOS. CONSISTENTES EN UNA FUENTE DE RADIACION INFRARROJA (11) EN LA PARTE DELANTERA (10) DE LA CAJA, CUYA FUENTE EMITE RADIACION EN LA MISMA GAMA DE LONGITUDES DE ONDA QUE UNA PERSONA HUMANA, SIENDO REALIZADA A MODO DE RESISTENCIA LINEAL O RESISTENCIA PTC, COMO BOMBILLA INCANDESCENTE O COMO LED, HABIENDOSE PREVISTO UNA VENTANA DE ENTRADA (2) DISPUESTA ALGO MAS ATRAS QUE LA FUENTE DE RADIACION (11), DE MODO QUE LA RADIACION DE ESTA PUEDE ATRAVESAR LA VENTANA DE ENTRADA (2) E INCIDIR SOBRE EL SENSOR (3) DESPUES DE SU DESVIACION POR EL ELEMENTO OPTICO (4). TIENE UTILIDAD PARA DETECTAR OBJETOS EN ZONAS CONTROLADAS.
