Hi there,
I’d like to make something that measures pressure either side of a water filter.
I want to hook up two pressure transducers to an Arduino (this one?)
to one of these:
(I have a gateway up and running)
I need help choosing which pressure transducer type to use.
I’m pretty sure I’ll use one of these:

I’m just wondering which output signal to use? Best? Easiest to work with?
RS485?
I2C (3FFF (10~90% or 0X666~0X399A))?
or low voltage (0.25~1.25VDC, 0.25~2.25VDC 0.5~2.5VDC, 10~90% Vcc)?
And what supply voltage would be best?
Any help would be greatly appreciated.
Thanks,
Martin
