So basically you have a hammer, so the task is to make every project look
like a nail, so you can use the one tool you have, But then you end up
using a A/D converter and FPGA and a Linux PC with a real-time operating
system to run an air compressor motor.
But all you really need is a comparator

Hello Gene.
This was a fun puzzle to find the English trigger on the web page.
On the fourth horizontal division of the web page from the top,there is the
line "Vende en AliExpress" (that translates to "Sell on AliExpress" ),

So you want to be able to control the air pressure from within LCNC? One
way is to have LCNC output a desired pressure then the air compressor just
does what it is told. Use a $4 microprocessor (even an Arduino would work)
to read the I2c and also read some output from the Mesa card. The Meas

This would be the sensor I would use. The link below is a very detailed
gud that tells you how to use the sensor, including working example
software.

Yes, it is an absolute sensor but air pressure on Earth does not c
Here ya go, choose whatever pressure range you want. But here's the
thing: most technical parts are now using BPT, aka "G"/DNx threads (not
to be confused with GHT "garden hose thread"). This is G1/4 aka DN8.
All the USA hardware store stuff is NPT (MPT,FPT) and they have the same

The 3 bar GM MAP sensor has been well characterized by the DIY EFI
community.
Linear output. 1.1kPa @ 0v and 315.5kPa @ 5v.

Greetings all;
I'm getting frustrated, but I know it has to be out there, someplace.
I need a differntial air pressure sensor, differential so it references
local barometric as its reference zero, and up to 10 psi, with a 3 wire
analog output.
I've solved the control aspect, but not how to detec
