create a vacuum / pressure sensor from 30" Hg to 3 atm.

A vacuum and pressure sensor that is Arduino compatible that can measure from 30" mercury vacuum to approximately 3 atmospheres pressure. It'd be great for those of us using Arduino as engine ECUs to be able to have fine-grained control of engine parameters by knowing intake vacuum or pressure. Knowing the intake cross-sectional volume, the intake vacuum or pressure (in the case of blown engines) could also be used as an intake air flow sensor, which will really be beneficial to those of us using heated water injection to create extra cylinder pressure via steam expansion (to measure if we're getting the water too hot prior to injection, thus flashing to steam before it hits the cylinder, thereby starving the engine of air by displacing the air with steam).

Hi DB:
We think this is a very professional area for the industrial control, would you please give us more advise about the popular sensors in this area, so we can make our products more convenient for you to use.
