Temperature sensor setup 1-26-14

Here is our current setup.  As the photo was taken, two sensors were writing to a PC console and SD card.  the thermistor is too small to be seen, but its leads are seen on the center, left side.  The 1-wire thermistor is at the bottom center.  It has 3 lines, but we are doubling up the power and signal line so we can use our 2 line cable.  The cables are about 3 feet long.  The whole system is working off a 9 volt battery.  The plug for the battery can be seen to the right of the SD card, on top of the Arduino.

Currently, the two sensors differ by about .5 degrees F.
