The five volt on board power supply this thing comes with
makes it real easy to wire up.

Here is the results of the first pressure sensor test. I used
a hand vac pump to reduce the pressure from sea level
to about 26 to 27 inches of Hg vac.
The numbers at the bottom of the chart are the sample numbers at
1000 samples per second. Data rez is to the nearest 1/1000 of a volt.
Seal level is 1.8 something while full scale is close to 4.5 volts.

This thing is real easy to use.

Mark, it would take all day to hand pump down a water jacket :)
