I know it. The problem is implementing that math in a microcontroller like an Arduino Mega. Even more difficult when the existing code already uses a lot of memory. Its so hard to implement, that Davis used an approximation, recurring to tables to avoid some calculations (of course the tables used are not published, at least I haven't found them anywhere).

Quote:Yeah it's a pain in the rear for sure. LOL. I have to wait until midnight so I can edit the log for today. Oh well, it's not the end of the world just some extra work.

So far so good. No fluctuations thus far that I've noticed. Hope it worked!

It seems you have removed the "clip anything below 6" which is good to test if the spurious readings are gone.
I will be following your webpage.
Whish you a good night. I will be back tomorrow.
