Anybody out there already set up one of these.
(WIN98SE machine, currently using WD 10.13K)
Not interested in re-inventing the wheel.
Objective is to have it plot relative brightness on the normal display plots.
How did you do it? Settings?
Previous posts refer to “solar flux” plotting problems.
What version has the plotting right?
Hi
this person has one
http://www.tokaanuskihire.co.nz/pukekohe/pukekohe.htm
i.e solar sensor with a dallas 1 wire
i,.e tick plot solar % in the graph setup, as well as tick plot solar
and , in the solar setup, tick, use the max solar radiation for time of day, and make sure your lat/long is correct under the sun/moon setup…
check those things
Thank you for the reply. The plot is what I am after. The downward spikes in the solar plot were of some interest. Passing clouds?
What is now unknown is how this was setup on the setup screen.
Was it called a “General purpose ADC” and the "use this as my solar sensor " box checked? I’m assuming WD will discover the ROM ID to put in the box.
I am at a loss why this has to be complicated by lat/longitude etc. When I did this years ago, the light sensor essentially had “zero” output when it was dark. There was no need to turn it off/on with known sunrise/sunset times. “Zero” output didn’t mean zero volts output from the ADC. It meant some defined dark value. What was measured was plotted–zero bias and all.
hi
yes, you need to set the rom id into the general purpose adc, then tick use as solar sensor, then go save exit
the use of the use max solar for long/lat for time of day is so that wd comes up with a % reading for that time of day compared to what it should be …
but i should be able to have wd plot the reading from the 1 wire sensor as converted to wm/2, but i dont know what that conversion is (from the mv to wm/2)
Thanks Brian.
Works OK.
The last time I was collecting sky brightness, my son was the age of 10.
The weather station saved him a punishment.
It seems we told him he had to be home before dark because riding a bicycle in the dark was dangerous.
He often returned after it was dark at home. His claim was that it was light elsewhere. It turns out he was right. There was a hill to the west. Comparing the true amount of sunlight we should have received to what we were receiving at the house’s weather station showed a 10 to 15 minute difference. The hill prematurely darkened the locality of the house.
He was right! No punishment.
Unfortunately, this didn’t kindle any interest in science in him.
