Abstract

La invención se refiere a un dispositivo para detectar la de humedad de un disco que tiene un sensor de lluvia óptico que detecta luz extraña y la evalúa para reconocer día - noche. En una etapa de integración (16), la cantidad de luz que llega al detector (14) se integra y se envía a una etapa de comparación (20). La cantidad total de luz compuesta de luz procedente de un transmisor (12) y la posible luz extraña, y la cantidad de luz extraña detectada cuando se desconecta el transmisor (12) se miden en intervalos de tiempo individuales (Tg, Tf, Tf). Después de un número predeterminado de ciclos de medición (M), o después de un tiempo predeterminado, el intervalo de tiempo usado para medir la cantidad de luz extraña se puede ampliar, y/o el umbral (S2) se puede reducir.
