thermocouple
On the right is an Arduino Uno microcontroller, with the Ethernet shield add-on. The whole is connected to my network with a static IP. The other cable is USB, connected to my desktop. At the moment, the USB connection is only needed for power, and so I can upload new code remotely if I need to. The arduino can function entirely on its own, as long as it is powered.
On the left, the IC is an AD595 Type-K Cold Junction Thermocouple Amplifier. It takes the input of the type K thermocouple, which is the coiled wire below the breadboard, and conveniently outputs 10mv/degree C, making it easy to calculate the temperature. This particular thermocouple is accurate to +/- 3 degrees C. I know the output on the page implies accuracy to two decimal places, but that is an artifact of using a float variable type. I'm going to fix that.
