Hi, I've been using the LMP91000 to test if it can detect various chemicals. However, when I save the data to file, there are no units for the data and it doesn't seem to correlate with the voltage that is shown on the graph vs the resistor chosen on the gui.
Any help is appreciated.
the LMP91000 Graphical User Interface saves the data in the following format:
Sample # | Data | Timestamp.
Sample # is simply the index (it starts from 0).
Data is a 16bit representation of the the output of the LMP91000. The ADC present in the eval kit is the ADC161S626.
Timestamp is the acquisition time in the format : hr_min_sec_ms.
