Thank you Matt, can I get a PM with more information regarding that?
I found this circuit while searching online:
**broken link removed**
This circuit seems to be almost exactly what I want (basically the analog voltage output), except that the given values for R1, R2, and R3 only measure up to 250fpm of air speed. No one on that website, or the original creator's website, has information on how to provide values for R1, R2, and R3. Anyone have ideas? I'm sending off an email to the original creator of the circuit to see if I can find out more.
