It seems to work perfect, in that it receives data, but I'm not sure what this data tells me.
I get a constant stream of numbers, mostly between 502 and 504 when nothing happens. When I blow on the tube the number increases to 550-600, or even up to 1000 when I put my lips on the tube and blow with force.
My question is now; what does this tell me about the air speed in meters per second? 500 seems to be zero air speed, but what does 550 or 600 tell me? Is there some kind of conversion table for this?
All tips are welcome!
