### ⭐⭐⭐⭐ Good sensor, innacurate specifications
            
*by A***R on July 5, 2019*

This is a good, apparently industrial grade sensor.  The photo shows the wire harness terminated with a JST connector - mine came with pigtails (with the automotive connector at the sensor as pictured).  The sensor connector backshell is not rigidly attached to the connector, so do not pull on the backshell when removing the connector - pull on the locking tab, or you may risk pulling out the wires.  I have the 150psi version connected to an Arduino Nano clone.  Sensor provides stable, linear output over the full measurement range.The seller has provided some confusing information with regards to specifications and capabilities.  The sensor is actually more capable than advertised.  First and foremost is is an ABSOLUTE PRESSURE sensor.  That being said, it will provide linear output under vacuum, and does not have any apparent hysteresis around ambient pressure.  In addition, the specifications are ambiguous  when it comes to the sensor response.  Here are my observations (based on a test setup using a mechanical gauge, compressed air, and reading raw sensor output).  Note that my pressure readings around zero were most likely affected by the hysteresis of the mechanical gauge:0 PSIG (Approx 15 PSIA) = 0.62V0 PSIA (extrapolated) = 0.11V - Note:  I was able to see smooth readings when I pulled a vacuum on the sensor, but did not bother to make any calibrated measurements under vacuum because my application doesn't require vacuum.60 PSIG (Approx 75 PSIA) = 2.48V100 PSIG (Approx 115 PSIA) = 3.84V135 PSIG (extrapolated - approx 150 PSIA) = 4.93Vlinear scale factors (5V supply, 10-bit):  1.047 kPa/bit; 214.3 kPa/Volt; 0.1518 PSI/bit; 31.09 PSI/VoltI used Libre Office Calc (Excel) to plot the data, then a linear trendline with show equation to get the slope.Raw Data:PSIG  ADC (raw, 10-bit/5Vref)0  12710  20420  24830  31140  37750  44760  50870  58280  65190  719100  786Hope this helps!
  

### ⭐⭐⭐⭐⭐ Works great!
            
*by T***S on July 13, 2018*

Bought the 100 psi model for monitoring my RO system using a computer to get around the inaccurate mechanical pressure switches.  Comparing this sensor output to a gauge in tandem leads me to believe the sensor is more accurate.  Both tracked each other from 0-to 70 psi (highest I want to stress my system) and the gauge reading is within eyeball accuracy of the sensor's reported output.I have no trouble with leaks but then it's only the 100 psi version.
  

### ⭐ Save your money and buy a better sensor.
            
*by B***T on March 11, 2018*

Ordered the 500PSI sensor. Worked for about 2 minutes, now oil leaks out of the connector... Save your money and buy a better sensor.
