Hi guys,
I just bought a digital multimeter with data logging from Jaycar.
http://www.jaycar.com.au/productView.asp?ID=QM1538
The software provided is crap. It will split each file up into 20 data
points rather than storing everything in one file that you can just import
into excel.
It has an inbuilt graph function that rather than making a grapgh from all
the points, will only make it from the last 20.
This makes it impossible to use it for what I wanted, which was to measure
minute changes in temperature over the course of a weekend.
I know that the multimeter itself is very good, it updates 4 times a second
and can give results to 3 decimal places, however the software doesn't take
full advantage of this.
I've googled and somebody said they used matlab to get better results, but I
don't have matlab.
Does anyone feel up to the challenge of writing cross platform software for
this? Or even just a linux command line thing that can also run on OSX that
would dump the data out in a format that graphing software could easily
import?
These are pretty much the cheapest data loggers out there, and if there was
good enough software you could use them as a cheap environmental monitor in
a server room.
I'm happy to help out with the project from a non coding perspective, such
as providing ideas and testing it (sadly I have little interest in actually
writing the code itself, so have never got around to learning a language).
Cheers,
Michael Brown
