Hi folks, been testing a new version of the night cloud sensor, well, its new to me trying it,
the idea i got off, Brian… thanks
Ok, for the past couple of night i have had chance to test Brians version (might not be exact)
with very good results, the normal jar version i made was ok, it worked, but with a smaller
clear sky difference, noramlly around the 0.9 - 1.5C range, with this newer version i have been
getting 3.0+ difference, perhaps its the cling film as opposed to a glass jar, or it could be cause
the black plate (painted polystyrene) is much large, about 80% larger than the inside lid of the jar.
This is the beta test and the beta with the night jar (not the bird )
Anyhoo, seeing as it worked well, i decided to scale it back some but the same idea
SO, i found a small bowl, drill a hole for the cable and 1 on each side to fix the whole thing to the fence. then paint it black (not all of it, couldnt be assed lol…
I think cut out some polystyrene to fit with an inch or so spare from the top of the bowl for the temp probe to poke through.
This next image is the semi finished sensor, styrene fitted with probe and made a small grommet for where the cable goes in, i have now bagged it as you will see further down, i used a ziplock bag opposed to cling film.
Next image is the holders for it on the fence, just some old brackets for roller blinds is all
And here she be sat in place all wired up, not tested, could end up being a lemon but thats just my luck after an hours messing about
