Wow, excellent work sir! Last 2 weeks I had a final-year project which required multiple pressure transducers. If I found your video earlier, the calibration for my sensors would have been much easier. But still, it can help me to improve my project's reliability. Thanks for the tips!
it is very nice and detailed tutorial. I am using almost similar setup. I am using 12V power supply but pump is not generating sufficient pressure. The cut off pressure written pump is 80psi but I am sensing the pressure reading fluctuating between 0-5 psi only. Don't know how to get higher pressure values
hello, I have a couple questions, first off I am building an HHO torch setup, I currently have it all wired up for just an off switch, but I want it to turn off/ cut power when it hits 5psi, I will be running my Arduino into this torch build so I can set the parameters as I need. my biggest problem is I need the code to enter and I don't know how to, can you help me with the majority of the code? and I will figure out the rest.
I think you're lucky it worked at all without an explicitly common ground. You can power from external, but need to tie the sensor ground to the arduino ground. Looks like it was, but used the mains ground as the path
Seems the pressure sensor especifications is for high pressure field and the power must come from arduino preferible than external power also for relay and water pump. However very nice set up.
I just wonder what good a setup like this is? I would think most would use the pressure sensor for a water level setup where they would want to turn a pump on and off according to a low/high pressure instead of what you're showing.
Is this rated for fluids other than water? EDIT: definitely think it will work well with fuel then! You're "hashtagging" ESP32, but you're using an arduino, so Im wondering if you just change the input voltage into the device for it to work with the ESP. 5 V down to 3.3 V? Because sensors are input devices to a microcontroller right? So the signal has to be what the device expects.
You have this wrong. The range of those pressure transducers if from 0.5V to 4.5V. .5V=0 psi and 4.5V=range of sensor. So you need to subtract .5 V and then divide by 4V. Any reading outside the range of .5 to 4.5 is an error. This is intentional with these transducers so you can detect a faulty sensor. Very misleading video showing people an incorrect calculation.
