A plastic shield to not max out the light sensor resulting in "unknown" messurments.
I am using this sensor in my window to guage is my cover should be up or down, but it got over loaded by direct sunlight.
So i created this simple thing.
There are a few thicknesses so you can find what works for you.
Note that this will effect the meassurment results you are getting ( not saying my sensor was right from to begin with, but the numbers will be lower then with out this of course )

The “loop” is if you want to hang it at a angle as i wanted to (see photos)
