    I am designing a pressure sensing circuit using SMARTEC SPD005G to sense 10KPA AND 1KPA pressure.

    This is the first time I am dealing with a pressure IC.

    The output of this IC is in mV and I will need to amplify it.

    However, I am not able to determine on how to distinguish the two required pressure for the same IC as for 10KPA the output should be an alarm and for 1KPA the system should shut off it will further be given to the microcontroller.

    Please help me as I have just graduated and do not have much experience.

    Read the datasheet, looks like it gives out 65mV @ 35Kpa, 140mV @ 100Kpa,

    Have you thought about using their UTI?
