<div><div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">I have been interested in Jim Mason (and company)’s approach to process control and datalogging using an Arduino based microcontroller since he first announced its existence. I have done a little googling about Arduino in general, and now I am sorta fascinated with it. I already have a fair amount of electronic hobby stuff around here, so I bought an Arduino ATMega2560 last week ($60) and am starting to get familiar with it.<u></u><u></u></span></p>

</div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">And, has anyone found inexpensive low pressure sensors? I can’t seem to find any in the +/- 20 inches WC range that are cheaper than about $40 in a 1 to 3 quantity.<u></u><u></u></span></p>
