I published a rain-sensor on my weblog.
As my girlfriend puts the laundry outside for drying I really like to know when
it starts raining, so we can get it in.
For now the sensors informs me of rain on a web-page (which can be viewed on your smart-phone), however this is an ongoing project. The rain-sensor will eventually twitter when it is raining.
And later on it will be coupled with my domotica system (Domoticz).
But for now it works.
The project is a bit large for publising here so I give you a link to my weblog.

Schematics and source code are included as usual as are the STL files for printing your own enclosure.
Have fun
