I'm looking for guidance on measuring two pressures P1 and P2 with an I2C digital pressure sensor. I'm trying to obtain both the gauge pressure for p1 and P2 as well as the pressure differential between P1 and P2.
Would the best way to accomplish this be to purchase a dual port Honeywell gauge sensor then measure the difference between P1 and P2 in software? I was looking at some of the digital I2C 1psi temperature compensated sensors Honeywell makes. Is there a sensor that does both differential and individual gauge pressures on two ports?
