That really shouldn't matter as far as mrtg is concerned.

Do not try to read data from a text file.  That doesn't work.  You
need to write a program that prints numbers on the screen.
Compare this with the "echo" command.  A small batch file could look
like this:

   @echo off
   echo 100
   echo 50
   echo some host
   echo quite some time

When you run this from mrtg (backticks!) and use the GAUGE option, it
should produce two horizontal lines: Target[x]: `c:/mrtg/batch.bat`

When this works, you're ready to write another program that outputs
the same way but this time with numbers you get from the sensor.
