Rabbit Powered 1-Wire Weather Station Controller (version 2)

My original Rabbit Processor based 1-wire weather station controller only supported the AAG 1-wire Weather Instrument. This version adds support for a humidity sensor, pressure sensor, and rain gauge. It also uses the Imagine Tools rabbit processor prototype board +5VDC power supply to power the The LINK and the 1-wire bus. A common 18VDC power adapter supplies both the prototype board and the barometer.

The weather instruments are mounted on top of my garage. The controller and barometer are located inside the garage and are connected to our RoadRunner broadband ethernet connection. The data is posted to the Weather Underground (KNYCLIFT1), Citizen Weather Observer Program (CWOP) station CW3725, and to our local TV station (CBS channel 6 WeatherNet6)
