I just purchased a MPXV7002DP airspeed sensor, and it's not being detected. Is there a way to determine if the sensor is any good?

My setup:

APM 1.0 running 2.12

uBlox GPS

XBee PRO 900

So it turns out that the value that's getting read off is too low. Depending on what kind of BEC I use, I can get values ranging from 2940 on higher. I just have to lower the 3000 value that's being used now to determine if it's connected.

You can test it with a 5 volt source and an analog voltmeter. You should see the voltage moving if you blow on the pitot tube.
