Hi guys - found this stalled here - I'm doing exactly the same project. Air springs need between 0-30-80 psi depending on where the ride height is going to be.
I bought a 4 button keychain remote/fob and it's wired. I can turn on/off LEDs just fine. What I want to do is use two of the buttons for different ride heights - one for driving normally down the road and one for cruising. (the other two are 'all up' and 'all down'.
So I have the NBPDANN150PGUNV and I get some funny readings when I pin it with +5v in pin 1, GND on pin 3, and A0 pin to pin 2. It jumps all over the place when I touch the sensor with my fingers (which is not the expected result) and if I use a straw to blow into the thing it doesn't register any change. What am I doing wrong?
I'm new to Arduino/electronics - so any help is appreciated. The datasheet is here for the sensor:
See Page 11. Not sure if I need something wired to pin 4 on the sensor?
