Monarch Track-It Pressure Pressure and Temperature Logger, Range 350 psi

received my sensor today... pretty disappointed because the description says "Red: +5V. Black (yellow): ground. Blue (green): signal output. " however the sensor has a Black, Red and Yellow wire and I have NO idea how to hook it up... and contacting the seller seems to not work either so hopefully I can get a response here on how to hook up my sensor.

Nice device. It can record and show live data on the laptop at the same time. The build quality is very good. This thing weighs over a pound. All stainless o-ring sealed lid and housing. It was relatively easy to program, and the results were easy to view and it printed a nice graph. The data could be saved and manipulated later by the program. The recording can be triggered by the button, alarm presets, and specific time/days. Very customizeable. I did not try the android app yet. It is far better than the old Dickson paper graphs we used to use.

This sensor seems to work well, I hooked the black wire to ground, the red wire to +5V and the yellow to a volt meter and sure enough it works. I am knocking 2 stars off the rating due to the weak plastic used for the housing, when I lifted the little locking mechanism to disconnect the plug from the sensor it snapped right off so it won't lock in place anymore. I have not measured offset and linearity but for what use it for it works OK.

I bought one of the 150psi model, It was DOA. I got a second hoping it was a fluke. The second one failed at 100psi and then read 0V. Avoid.

Awesome product! Programming is a little cumbersome.
