Making it!

  • This is kind of a complex question, but I'd like to use two of these to act as a kind of Prandtl tube for determining the air speed coming out of a blower. Here is a good description of a what a Prandtl tube is and what it does.

    A prandtl tube basically compares ambient air pressure to the air pressure in the direction of travel to determine air speed. This is a drawing of what I am thinking I would do with two of these sensors:

    I was thinking I could install one sensor on the outside of the box, and one on the inside, to determine the air speed coming out the front of the box. However, I'd like to try to do this with out interrupting the flow of air as it moves. I realize this might be a bit beyond the scope of the tutorial, but do you think there would be a major difference in pressure readings if the sensor was flush versus directly facing the flow of air in a tube?

    Also, when hooking up two of these sensors, would I be able to connect two using only one redboard?

No public wish lists :(
