I've got a collection of 1-wire gizmos and USB thumb drives. They are great
for many applications but I'm looking for something better/different. I'd like
something that reads to 0.01 degree or 0.001 degree. I don't need accuracy.
What I want is reasonable linearity so I can make pretty graphs. I'd like the
actual probe to be small enough so I can poke it inside gear like a PC and
attach it to a crystal. I'm looking for a USB or serial connection so I can log
the data. Is there an obvious brand/whatever I should be looking at?
thermistor? thermocouple? ... I don't care about a display on the device. I
don't want a logger, they fill up. I want to grab the data on the fly and do
my own logging. (But I'm happy to use a logger if it will do what I want.) --
These are my opinions. I hate spam.
