How to use this pressure sensor?

  1. Feb 19, 2012 #1
    I feel really stupid for asking this.. but how does this sensor work? I'm not really good at electronics.

    What I mean is, if I have air flow through a pipe, how would I use this, through the small pipe that comes out the top? Or maybe put it inside the tube? Or is this an atmospheric pressure sensor?

    looks like it's an atmospheric pressure sensor. supply voltage to it, and then read the voltage from the output pin

    if you want to measure pressure in a pipe, i'd suggest using really big pipes.
    other options include looking for some kind of in-line pressure sensor
