Hi,

At First :

Vout = Vs* (0.00369*P + 0.04) ± Error

..Wich I thought would be the same as

calcpress = ((( pressure / Vs ) - 0.04 ) / 0.00396 )
Don't you see something strange ??? ...


I want the value in kPa or Bar.
You will display Bars or KPa ... but certainly not calculate with Bars or KPa ...

May be calculate with Pa ... will give a decent result.

BUT ... wouldn't it be best to work with ADC Units ( 0 -1023 ...) and ONLY convert to Pressure for display purposes.
