Here, the illumination sensor device 1 is disposed in a state where the attachment reference lines L1 of the respective instrument bodies 2 are positioned in parallel. In the present embodiment, the two illumination sensor devices 1 attached to the two adjacent circular holes 25 in the lateral direction are positioned such that the respective attachment reference lines L1 overlap on the same line. In this positioning state, the two plate spring members 20a, 20b of the instrument body 2 are fixed to the ceiling surface 24 by fasteners such as bolts.

  During the operation of the illumination sensor device 1, as shown in FIGS. 4 and 5, the inside of the illumination space such as the room of a large scale office is observed by the imaging sensor 8 and the pyroelectric sensor 9. In FIG. 4, an observation area by the first lens 11 of the imaging sensor 8 expanding downward from the ceiling surface 24 is indicated by an expansion angle α, and an observation area by the pyroelectric sensor 9 is indicated by an expansion angle β.
