I got an email today asking "Could you consider posting wetbulb like frogville. This is valuable for guys using evaporative cooling."

First of all, Frogville is another site in Southern Arizona using a different software than Cumulus. Next, I have no idea what make this wetbulb this work. Is there such a thing a wetbulb for Cumulus or Saratoga Template systems?

Yes, Cumulus does produce a wet bulb temperature tag. In the Saratoga template, it shows as $WX['wetbulb']

On a page where you'd like the value shown, just use

Code: Select all

<?php print "Wet bulb Temperature ".$WX['wetbulb'].$SITE['uomTemp']; ?>


I'd not included a $wetbulb value in the CU-defs.php, but using $WX['wetbulb'] works just as well.

Hope this helps...

Best regards,
Ken

What is involved in setting up a "wetbulb"? I assume there is some equipment that is required. Would that equipment need to be attached to my Davis weather station or how does it communicate to the "$WX['wetbulb'] " code?

It's calculated from your outside temperature and humidity. No additional sensors required.

Thank you, Steve. I will add that code to my site. Then I can be up there with Frogville. With our climate, this is importat information (so I am told) for those people who use evaporative coolers instead of air conditioning.
