[Weather] dual drains -- was Re: conversion help

[Mark Richards]

There's a discussion going on about a "rain plate" here: 
http://www.halfbakery.com/idea/Home_20weather_20station_20with_20bucketless_20electronic_20rain_20gauge

Tis a very cool idea, but I think this description is tops:

"Assign each raindrop an ipv6 address and a very small RFID tag that 
broadcasts the address. Upon impingement with, or near, the raingauge, 
the recovered IP address is used in a query to recover the properties 
stored in the raindrop database for that address, in this case, the 
water volume of the particular raindrop.  	

The volumes are aggregated over time and divided by the number of 
recorded droplet impacts to calculate the total volume of rainfall."


I'd take it one step further and store each raindrop's properties in a 
mysql table allowing historical analysis and graphing of the data, too.
