Temperature Compensation

Has anyone added a temperature compensation function yet??

Shure, why not...

Use the circuit below. No hard to find pieces , cheap and small sensor too

For the diode probe use a piece of shrink wrap tubing for waterproofing

The results for my probe are plotted on the next graph

The precision is pretty good if you make a 2 or 3 point calibration like the one on the above graph
