Temperature Sensors for Linux

The DT1A temperature sensor module is a PC board mounted DS18S20 temperature sensor with two RJ-45 connectors. The board has a reverse biased 1N5817 Schottky diode and jumpers for parasite or +5v powered operation. The RJ-45 accepts a standard 8 position ethernet cable, or telephone style RJ-11 connectors. By default they are configured for passive power to the DS18S20 sensor. The diode helps clamp reflections at the end of long wire runs, preventing glitches on the 1-wire network. If you are interested in building them yourself you can find instructions here. The Eagle Cad PC Board files can be found here.
