Industrial Pressure Sensor - Arduino

Hello and congratulation for your video. I am using a Honeywell 150psi 0.5-4.5V (ratiometric) sensor and as far as I understood the equation should be: psiVal = (37.5 * voltage) - 18.75. Is that right? [or... psiVal = (voltage - 0.5) / 0.02666 ] Also because I am using an Uno R4 Wifi and the transducer is very accurate according its specs, the aRef could be 5.00. Am I right too?

Thank you! Any chance one can pay you to come up with code/arduino solution for compressor and air pressure control which is adjustable via the buttons and screen?

I love that you can just directly plug these across the arduino 5v pins and put the output cable into an analog pin and it just straight up works

Well explained, thank you! I am currently working with a 5000PSI pressure transducer (Output voltage 0.5V-4.5V) and the Arduino NanoEvery. I have some questions; do I have to test my pressure transducer before creating the code or it can work with your code? Why do you use 4.6 as your X1 instead of 4.5? What is it the thing you are using to connect the pressure transducer to the breadboard, and it has a capacitor inside?

I am just coming across this video and it's absolutely amazing. I am learning about all of this in hopes of make a oil pressure/ boost gauge with negative pressure with a small 2-1/16” (52mm) circle lcd screen , I am stumped on the coding to get not only the value change but possible having its set as a normal gauge with a lcd needle sweeping across the gauge similar to a big hand on a clock

Greetings, I want to configure this air pressure sensor to a leg pressure cuff in my project. Is 100PSI doable for my project? Thank you for the wonderful video.

i am tempted to buy the 30PSI version of the walfront sensor, but i am unsure how it operates it's output when i can only supply 3.3V since i am working from battery ... can anybody tell me or recommend an alternative transducer that outputs voltage or is even digital !? 30PSI, 3.3V liquid

Incredibly helpful video. I'm currently working on a project involving measuring burst pressure in membranes, and ideally would like to use a pressure transducer to measure the pressure inside a tube and record/plot the pressure over time on a computer. Do you know how I could set up something like this?

With the right fitting be put inline on a 1/2" copper pipe?

Also, will this code work on an ESP32?

how do i get psi to bar in arduino IDE?

I’m looking for a sensor to read small gage pressures in the range of 0.01-0.02 bar. Do you know any sensors that can read these small pressures.

Your contribution is very good. Could you tell me where I can find information to program 5 sensors simultaneously and be able to change the reading unit? (to be able to pass it from psi to bar)

i need someone to work with for vacuum and flow measurement

Hi. Thank you for your interesting video. I found it while searching for Vacuum sensors for Arduino. I wondered if you could advise me on what I require?
I want to test the vacuum in a chamber as it’s being evacuated out of the chamber so I can stop evacuating when I’ve got to the pressure I require.
There are so many to choose from and with little to no knowledge on the sensors I’m unsure.
Again an interesting video. I’ve liked and subscribed 👌

Great lesson with analog read, voltage conversion, lowpass (though I think lowpass code in video is wrong) concepts, etc. But for both accuracy and code space on a micro - would it not be better/easier just to take your reference ADC values and map those to PSI?

You skip the need for reference voltage offset/measurement, rounding, variable space and cpu cycles for the conversion to voltage.

For Arduino with 10 bit ADC and example sensor (say 0-150 psi) you record ADC readings of 18 at 0 psi and 987 at 137 psi (or whatever). map (sensorval, 18, 987, 0, 137)
Fewer variables, no need for point slope, etc. (Assuming a linear sensor response).

can I use this sensor to measure the vacuum?

hello, is it possible to measure the milli bar? If so, how should the code be?

can this sensor be used to read negative pressure?
thanks

how much psi are hold up by arduino? I need to make a dispositive that receive at least 290 psi

can I ask how to input the TI-84 Plus ce to program

Hi i have a question regarding one microfarrad capacitor. Is it a ceramic capacitor and second thing is. Is it safe to use 0.1 microfarrad capacitor since I am a bit new to this therefore I wanted to know.
Approximately how much current will the 0.1 uf Capacitor will generate . Shall I connect one end of it to ground and the other to the incoming voltage signal of the sensor.

I need your help please comment.

Hi again Mr.

I acquired a SPI blue OLED display, of 6 pins (GND, VCC, SCL, SDA, RES, DC) but when I connect A4 to SDA & A5 to SCL, the display does not show anything; the screen remains in black. I tried to invert the connections, but does not work too, because the display uses de SH1106 driver
What do you recommend to do ?

Hi Mr

Excellent explanation.
I write from Mèxico and I would like to know what sketch changes do I have to do if I use a pressure sensor with a range from 0 to 232 PSI
If you can help me, I would appreciate a lot
Another. Where did you got the SPI display ?
Do you connect the display wit A4 and A5 of the arduino ?

Thanks in advance

Hello, excellent video, how can I use a 174 psi sensor, I'm only interested in that value,. I speak Spanish, sorry if my translation is not very good, but your video helped me a lot.

Can this type of sensor be used for a submersible to find the current depth? I guess I would have to have this sticking out of the hull somehow.

Thank you very much for the vedio, very helpful, please I Need your advice to use such system to measure and control air pressure inside plastic containers, I need the unit to be as a air leak tester, it it possible, for your comments please...Thnx..,

Which arduino board are you using and which pin is connected?
Thankyou

Hi
I'm using such sensor too.
I'm calculating the pressure:
pressure_temp = mapfloat(adc, 0.0, 4095.0, min_pressure, max_pressure)
pressure = a * pressure_temp + b
This is bad? (min pressure 0, max pressure 100psi)
a = 1,4 b=0,4 about

hello, excellent video, how can I use a 200 psi sensor, I'm only interested in that value, thanks friend

so nice

Great video. I've been working on something similar recently, and I have no idea why I neglected to think of using a low-pass filter to smooth out my sensor data. Had been working between doing both rolling averages and rolling medians and was quite unhappy with both. Now, I am pushing detected pressure changes out to my MQTT server less frequently, as the drift in my voltage is less than 2mV (hence, much more stable pressure readings). Thank you!

Thanks

Cool video
