Wow this is promiscuously cross-posted...


I too am looking for a voltage data logger with USB output and
software. I can find some fairly inexpensive thermal loggers like
this, but nothing that is, say, a 200mV input logger.
The thermal ones I have seen look like a USB memory stick.

Where you can install a computer, one could use 1-Wire devices
and software like 'digitemp' or roll-your-own.

For standalone, I have used educational data loggers like
the TI CBL and serial-port interfaced loggers from the likes
of DH, Vernier or Fourier, which for the more general purpose
models include a 200mv range.
