Hi all, I have above air flow sensor that I'd very much like to use with the Arduino, but after reading the datasheets and searching the forum, I do need help hooking it up. Programming is not the problem, but my lack of electronics know-how. It's sitting here waiting to have a blast (of air)!
While I'm at it, maybe someone knows a good source for the appropriate 5 micron filter.
My main reference doc is attached below. It should contain all relevant info.
Voltage vs. Output on page 3 - min / max are -80 / 80 mV (Don't need the neg. value.)
- What would a smart amplification circuit look like?
Wiring diagrams on page 4
- I guess the unspecified resistors are internal?
- The little house-like symbols must represent the sensor pins?
- And I don't understand which pin provides the output Voltage! (Argh.)
I'd very much appreciate your help!
