That's great. Looks like a super-simple solution.
You didn't need to solder on any kind of pull-up resistor? Did it come with instructions about which terminals on the phone cable each of the legs on the sensor went to, or did you have to figure that out separately?
No resistor. There are very good images of the wiring diagrams on the hobby boards site *where I got me adapter. And I still accidentally wired it backwards, with no seeming ill effects other than it just didn't work.
About the only thing I think I would like better is better instructions from the guy who wrote the Logtemp software. It's very capable, and for the most part not too hard to figure out, but I wish there were more tutorials to help you out.
Here's a couple of shots of the hardware:
You can see how tiny this thing is, and how it's wired.
Here is the USB adapter, which communicates with each sensor on the network. You can daisy chain multiple sensors easily by connecting the data wire from one to the next. They each have a unique hardware serial number, so your adapter always knows which one it's communicating with, and there is no need for more than 1 wire since it's polling based on the serial numbers.
You can also see the standard telephone cable. You could wire a CAT5 network cable in here as well if you had a crimper and basic wiring knowledge. This setup so far has only a raw sensor. They also make these things prebuilt with a sensor on a small board with 2 connectors, to make wiring super easy. One cable goes to the adapter, and the other goes to the next sensor. I chose this way because I wanted to be able to place the sensor directly into the thermowell. The telephone wire is too thick, though, so I'll have to replace it with something that will slide into the probe better.
