Thread: Tutorial - Air Ride Suspension

resistor size doesn't really matter, as long as you use one around 100 ohms. you then use the voltage divider formula and resistance to PSI conversion posted above in MDX to get PSI

nick might make a function that does this automatically... would be pretty sweet.

like a curvefitting function

Are you talking about the
airridepressuresensormodule.xml
airridepressuresensormodule.designer
files

As far as i was aware they do the job of taking the input (voltage) and converting it to the Output (Psi).

Is that not correct?

Thanks
Ken

those will work if Nick posts the resistor he used while building those files

nick confirmed: his code is based on a 100ohm resistor.

perfect. thanks for that

Hmm ive got this thing wired up like my diagram above and i am getting a reading of 452, surely on a 150psi unit that's not possible.

edit
This is the airridepressure function:

Ok im going back to basics here.

Forget PSI for the moment, lets just work with voltage, if i open up the standard skin and plug in the sensor on its own with no resistor and no PSI converter i get 4.87 which is the volts obviously

However if i then install the 100ohm resistor, that voltage should still change to a much lower figure surely, well this doesn't change at all which leads me to assume ive got something wired incorrectly.

Is there anyone out there who has actually got a pressure sensor working on this FB board?

Ive got it exactly wired as in my picture above, can anyone shed any light on the subject as ive hit a wall right now.
