This is a dusk sensor enclosure. The main unit has holes for screws and the top slides on.
This is installed outside and is used to steer the orientation lighting in a house.
The circuit is a simple 741 opamp with 2 LDR's and a resistor divider where the opamp steers a transistor as switch.
The LDR's are installed in a tst tube which is glued in the enclosure with a lot of TEC7 (silicone glue) t ensure watertightness.
Note: the margins where to little so quite a bit of sanding was required to make the top slide on. This has been corrected in the STL.
