Sensors and Interface cards for data logging

| I would like to start setting up to monitor system parameters using a
computer. I have gotten an older computer, and put all new programs on the
bare HDD. I also have copies of "Visual Basic' that I can use to set up the
programs, output, etc.
Now I need to get the sensors and interface cards. Can I get you folks to
help me here?

The devil is in the details. For cheap, rudimentary monitoring, I am
attempting to use these for A/D:
http://www.dataq.com/products/startkit/di194rs.htm
The biggest problem with them is the onerous terms of the license
associated with their included software, which I declined to accept,
so I had to write my own.
They also have other versions, at increased price.

Some USB stuff for $100.
Cheers

Just what is it that you want to measure? I've heard people do pretty
well with the 1-wire and I-button stuff.

| Per the OP, I am just starting into this area. My goal is to develop some
facility with data logging and measurements over longer time periods (e.g..
longer than I would hold a probe on a point).
The first reply posters suggestion to look at Dataq.com was good and I was
ready to move on their "Data Logger Starter Kit" with some temp probes until
I realized that I also needed a $200.00 conditioner, which is too pricey for
me.
Steve Spence's suggestion that 'basic stamps' might be the way to go
looked good, but looked like there was a long learning curve to crawl up to
get things running. Maybe in a few semesters when I start into micro
controllers and such...
Is this going to turn into a time or money thing? I sure don't have much
of either.

I'm not sure what you mean by that. What sort of "conditioner" is
needed? I'm just hooking the A/D to some LM35's. There are some
mods on the Web to change the range of the A/D to better match the
output of the sensors.

Probably.
I looked into dataloggers and BASIC stamps, but felt the pricetag was steep.
So I spent some time to work with Dallas' one-wire technology, and since I
program for a living, setting up Linux and some C code wasn't much of a
learning curve.
You get's what you pay for (in either time or money).

| I use 2 supco loggers for my heat pump. One is pressure the other is
temp/humidity. Great if you don't have to have real time monitoring.
