PYRHELIOMETRIC SENSOR

摘要

This invention relates to a pyrheliometric sensor used particularly for control of an air conditioner mounted to a vehicle, and aims at providing a pyrheliometric sensor capable of precisely controlling and detecting a pyrheliometric heat load corresponding to the direction of solar rays. A shading film (23) is formed on the upper surface of a transparent substrate (21) (inclusion member) of a photosensor device (12), a light introduction hole (24) is formed at the center of this shading film (23) and photo-detection portions (22L, 22R) are formed on both right and left sides of the lower surface of the transparent substrate (21).
