Dusk sensor enclosure
thingiverse
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.
