It all started when Dallas Semiconductor Inc. (now Maxim) offered their WS-1 Weather Station to the public. The WS-1 is a inexpensive weather instrument that measures temperature, wind speed, and wind direction. It was designed to show off the capabilities of their new 1-wire bus. It quickly became the gotta-have-it toy for weather hobbyists world-wide. Since its introduction, hobbyists have designed additional sensors including Humidity, Barometric Pressure, Lightning Detection, Rainfall and much more. Many offer their sensors as schematics, kits, or completed products.
Dallas no longer sells the WS-1, however an updated design (version 3) is available from several vendors for about $80. See the Resources section below.
