How to cobble together a datalogging thermometer with high resolution
The commercially available models are either prohibitively expensive, or they don't datalog. I'm trying to figure out why SOMEONE hasn't come up with a USB-connected widget that you can plug a high-precision RTD into and log the resulting information.
What I'm looking for: A combination sensor (probably RTD?) and data acquisition system to log temperatures with 0.001C precision. Accuracy isn't a huge deal, but being able to calibrate around 0C and 100C would be adequate.
The Traceable 4000 would be great, but it doesn't allow for datalogging in an automatic fashion, i.e.: sample data once every second or whatever.
If anyone has any words of wisdom, I'd love to hear them. Bear in mind I'm just slightly past the point of knowing not to hold the hot end of a soldering iron, but I do know the basics of electronics- just not much on the digital side of things.
