My main question is finding the pinout for vacuum sensor MPS20N0040D-D (as found on ebay and aliexpress) or a similar vacuum sensor that would also do the job. So far various extensive searches yield a whole lot of nothing. Seems to be the norm with cheap Chinese parts. It's really not a big deal for this project.
(Digikey has one, but at 10 times the cost and has two more pins-I can go that route, but for now I want to keep it on the cheap.)
I would like to connect it to my arduino uno analog inputs. I should be able to slog through the workings, so at this time I am simply after the pinout, but if knowing what I am up to helps, read on!
The project:
Carburetor balancer.
I've got 2 side draft carbs on my car (see my avatar pic). Carb balancers are available, but they are mechanical. I've just discovered the Arduino and may as well make an electronic version, right? Why not?
I'll need 2 vacuum sensors with some sort of readout from the Arduino, whether the 16x2 LCD display I have, or connecting in two 4 x 7 segment displays. Probably need 1 or two pots for calibration and zeroing.
An additional feature I would like to add is bluetooth output to a custom android app.
how I see it working:
Hook the vacuum sensors to the carbs via tubing, have a kPa readout for each sensor.
Thanks for your help, ideas, or whatever you feel like slinging at me.
Hope I've included enough info.
