Hi Team,

What kind of data(for example voltage of sensor) can be gained through LMP91000 Sensor AFE Software after connect the LMP91000EVM to SPIO-4 board?

Beat Regards,

    Tom,

      Depending on the sensor you are using, you will get a voltage out that represents the gas level the sensor is detecting. Read the sensor data sheet to get an understanding of what that value should be.

    Most designers, begin with the incorrect settings for the LMP9x board. Use the GUI Software to find a sensor that is similar or the same as you are using and change the default settings to these values to begin. Only if you are using a standard solution with the sensor can you know exactly what value you should be getting. Adjust the settings until you get the correct voltage feedback.
