7) To install the light sensor, drill a hole with a diameter of 14 mm in the wall of
the poultry house. The best place to mount will be on the wall facing the
most sunlit side. Insert the sensor plug through the hole in the plate [G] and
move the rest of the cable, then slide the plastic nut over the cable and screw
it on the sensor's rear housing so as to fix it on the plate.
8) Insert the plug through the opening in the wall with the sensor pointing
outwards. Pull the entire cable through and fasten the sensor board to the
wall with the screws [E].
