(mods sorry its here as i cant post in the originating forum)
Hi
im posting this here as i cant post in your thread( i signed up to answer you post)
Looking at the formula i cant do not into maths, however all you need to do is measure the output from the probe at at known temp, ie 25degrees c in a ph7 solution then measure in another ph solution then build a table from that, at 25deg c there shouldnt be any temperature compensation needed, but not all aquariums sit at 25degrees .two sites bellow have a good write up (sorrry if its too simple)
http://www.66pacific.com/ph/simplest_ph.aspx simple ph circuit
http://www.sensorex.com/support/more/ph ... _education nice temp chart
check around the saltwater forums as a lot of people are building diy aquarium stuff so an easier answer could be found there
also look out for aquatroller source code is online although written for an arduino and in c ,if you look at the code his ph solution is in there you should be able to modify it for use in your programme
hope this helps
dazz
