Updated a few days after usage began:
Sensor failed, and now reports erroneous readings, generally notably negative pressure in open air. Sensor was connected to tap water at about 10PSI.
Junk. Do not buy.
------------
Performs exactly as expected.
When powered at 5.00V (red), output (yel) was 0.513V at ambient pressure of 29.85inHg. Output is ratiometric with supply voltage. Current consumption was 2.07mA. Note that this sensor responds to absolute, not relative pressure, so barometric pressure changes will affect it when in open air.
If you're an Arduino user, you'll get excellent results powering this from AREF yielding a resolution of 30 PSI / (0.8 x 1024) --> 0.037PSI.
Supplied cable comes with short lengths of wire -- my photos show extensions added for Arduino usage. Note the shrink-wrap also over the outside jacket as that cable has an exposed shield layer.
Included image shows extra fittings added for connection to 1/8" irrigation tubing. Sensor has 1/8" male NPT fitting.
Aurduino code follows:
/*--------------------------------------------------------------*/
/* Water pressure sensor. Ranges 0.5-4.5V for 0-30PSI. */
/*--------------------------------------------------------------*/
int water_pressure_ticks;
int water_pressure_10mPSI; // pressure in 0.01 PSI units
#define PSI_0_MV 500 // millivolts at 0.0 PSI
#define PSI_30_MV 4500 // millivolts at 30.Read more ›

Out of the package with exactly 5V applied to red/black yellow is at .405V completely unloaded.
If this was sensing absolute pressure as another reviewer suggested I'd expect a reading somewhere near my absolute pressure today (29.95 inHg altimeter setting @ 980' -> 28.9 inHg absolute) of about 14 PSI. On a 30PSI scale with an output range from .5V (0PSI) to 4.5V (30PSI) this should come in somewhere around 2.5V. If this were the case its reading slightly negative absolute pressure (not a likely condition) right out of the package.
I'm guessing from this reading this is gauge pressure (the measurement cell is open to the atmosphere). I attached it to a couple of mechanical air pressure meters I have and a bicycle pump on a manifold -- when the meters show around 30psi I get an output voltage of 4.64V. This does seem to approximate the 30PSI stamped on range, 0PSI (gauge) == .39V and 30PSI == ~4.64V.
I'm going to try to use this to measure pressure on a swimming pool filter system so absolute accuracy isn't all that important, just repeatability. If it survives a test on street water pressure for couple of weeks I'll buy a few more (and some spares) to complete the project.
The schematic in this listing appears unrelated to this device (I *wish* it had a digital output).
--------------
Update after a few weeks deployed:
The 30PSI senders *all* failed (either to ground or +V) after about 2 weeks under pressure. The pressure is about half the rated pressure, maybe there's a startup transient when the pumps start (this is in a pool filter system) that burst them but on a mechanical guage I don't see any pulse. I'm trying an 80PSI now but at this point I'd say the 30 PSI units are either defective or not designed to run in water at 18PSI continuously.
Attached a picture of one of the failed sensors as installed (a failed one).
