Abstract

Avisador PIR con una lámina de ventana (2), un sensor PIR dispuesto detrás de ésta con la electrónica de evaluación correspondiente, así como un diodo emisor (28), un detector (28'') para la radiación del diodo emisor (28) recibida después de la dispersión de la misma y un circuito que compara el valor real de la radiación detectada con un valor nominal, caracterizado porque el diodo emisor (28) y el detector (28'') están dispuestos en diafragmas tubulares que están separados entre sí y se encuentran junto a la lámina de ventana (2), porque el diafragma del diodo emisor presenta una abertura lateral (32) para que salga una parte de la radiación del diodo emisor, y porque el diafragma detector presenta una abertura lateral (32'') para que entre únicamente radiación dispersada en la lámina de ventana 82).
