Review on Zreneyfex Pressure Transducer Sensor Water: Accurate and Reliable Water Pressure Monitoring by Paul Andrews

Not very good quality. I have two units that differ significantly on things like the chamfer around the hole and the size of the hole itself doesn't matter, just a bit odd. Plugged them in and tried to get readings on my Arduino. I had a problem when I noticed that the three wires are the same color but on different pins. OK. So I figured out what combination might be the right one and hooked everything up. Sensors didn't read linearly back then, the best match I could make was a power function. Again nothing special but I don't feel like I should. They work, but I wouldn't recommend buying them if you're looking for something with some sort of documentation or something that works as advertised. They're cheap and they work. But you need to research and develop something that should work after calibration. Edit: Figured it out and read everything and now they don't work at all. Not quite sure what happened. Don't waste money.
