Barometer setup question

[beanie]

Hi guys,

I'm currently working on a large barometer for the side of a building using a MIAC with Advance sensor module lo connect the vernier barometer sensor.

From the data from IDS who made the matrix sensors it states that the sensitivity is 435mV/inHg and across the scale of the reading this gives less than 2.5V across the scale. As the system is 5 V as is the ADC that is being used to read it I'm stuck as to finding out a reference voltage to class as minimum, if anyone could help me with this I'd greatly appreciate it.

Cheers

Matt

I've had a response from IDS who have given me the following information so I thought I'd put it here for future reference

Slope is 2.292 Intercept is 24.215 for inch in Hg

INCH Hg= raw voltage*2.292+24.215

e.g. 1.732 Volts is 28.18474 inch in Hg
