Using Instrumentation Amplifier(InAmp) chip is better than build InAmp from general purpose opamp(GPO).
I tried build from GPO with 1% resistors, but the result is not satisfy, the gain is too far from what I want.

Hi,
i using this schematic for MPX2010D and is work fine, i do correction parameters (offset and range) with autocalibration by soft.
Instrument amplifier is better, yes, but more expensive too.
All depend about application goals.
regards.

I haven't found the project
In the .rar file there are 10 projects but none use the mpx4150 sensor

If you are looking for barometric sensor I suggest you to have a look at:
www.hoperf.com
www.wti.fi
They have cheap sensors a lot more accurate than the Freescale ones.
