You mentioned a little while ago in a posting about how to make a solar sensor, using a glass jar and placing a solar sensor in it.
Please could you clarify a few points please.
- You need to paint the bottom of the jar black. So, if the the glass jar is up-side-down, it would I assume be the lid painted black inside, so that the glass jar exposes the maximum sunlight into the jar.
Could you confirm this is correct.
2)within WD Solar Sensor set-up, what does the “update max solar value from this max reading for lat/long, daily”, as it appears nothing happens if I check the box.
3)Where and when would I use the offset for tenths of degrees C for this temperature sensor
yes to the first part
update max solar: it updates the maximum expected solar reading daily for your location for your lat/long, so that the reading wd caculates from the temperature sensor in the glass jar has something to compare too…
in the solar setup, try setting the maximum thresold to 13 /1 and the lower to 1 /1
Thanks Brian, I shall try that.
Can you tell me also if the total sunshine hours should be recording on the daily report of July2003.htm, as it is not? Likewise, are the minimum/maximum soil temperatures recorded in this file too?
the soil should be there…do you have a soil sensor set in the extra wmr918 readings window?
sun:
well, its only approx, and not really all that reliable, so i dont have it going out onto the internt
Nope. the soil sensor is set-up in the view/wmr918 extra sensors, and it is reading okay, but it certainly is not showing in the July2003.htm file!
try giving it in a name in that same wmr918 extra sensor window
Have named the sensor#2 as “Soil Temperature Sensor” already
ok, the solution is to go to view, averages/extreme, and tick i have a soil sensor
Thanks Brian, I have now done that. I assume therefore this will also show and correct in the “All Time Records”, as this still shows as “Record low soil temperature as 0.0C” although the high is recording correctly.
I will let you know when the 24hour rollover occurs how it updated, unless I can force this another way.
try resetting the all time record low soil temperature, via action, reset all time records
you can force the averages/extreme to update via action, update the averages extreme
