1-wire is a great technology for homebrew weather stations and environmental monitoring in general.

Once you get a 1-wire master, you can chain devices on a single cable (e.g. the ubiquitous DS18B20 temperature sensor). Digikey, Adafruit and Sparkfun have plenty of breakout boards and it's pretty easy to find code either bare metal (bit banging) or linux I2C

There's a pretty good intro book by Tim Bitson: https://www.biblio.com/weather-toys-by-bitson-tim/work/56888...

And some interesting projects such as this 1-wire rain gauge: http://www.midondesign.com/Documents/1wire_raingauge.PDF
