This is how I have mounted the 1 wire solar sensor
I first cut off the photodiode, that is on the hobby board circuit board please make a note of the polarity
you will see a small indicator on the diode please make sure this is wired exactly the same way
Solder two wires onto the photodiode thread the wires through a small white tube and then apply
some sealant in the top of the tube then push in firmly so you see the photodiode protruding above the tube
Make a small hole in a table tennis ball apply some sealant around the hole and push in the photodiode
which is housed in the small plastic tube
I decided to use a white circular disc in theory this should reflect the light when the sun is positioned
at a low angle I have drilled a hole and pushed in the small plastic tube into it
I then mounted another tube into the waterproof box , on top of this I have mounted the white circular disc
which has the photodiode tube mounted into the table tennis ball
Mounting a 1 wire hobby board solar sensor
The plastic tube to mount the photodiode was the body of a white plastic Biro pen
Circle was cut from some 5mm white plastic I had lying around in my garage
Tube coming from the box is standard electrical plastic conduit pipe
