I would like to put weather data on the internet and need a general overview of devices/methods used. I have barometric pressure and temp, RH, wind and Wind direction available as per the USB weather board. I have the ethernet board (not shield) and have played with them separately with the assumption that they can talk to each other via I2C or other method. Is this the correct approach?
Sensors to Arduino to network board to web is a likely solution.
Have you visited www.pachube.com?
Yes I have and that’s the goal. Gotta figure out how to get data to the ethernet board first. What’s the first thing to learn, wire.h?
Weather Underground - is a server with thousands of home/school weather stations pushing data to it, at fairly high rates. It archives, and produces various graphs via a web site.
My weather station (La Crosse brand) has been pushing to that server for years, and also writing to a local MS Access database. This is done by my always-on home automation PC, with a little of my own javascript + some freeware to talk to the weather station. Now I have a new WS28xx La Crosse and it’s simpler yet to do this.
Example
http://www.wunderground.com/weatherstat … KCASANDI77
with browser tabs for various date ranges, graphs, tables, etc.
Any comments or suggestions on using the wind/rain sensors, such as quality, reliability, or accuracy. Could I use a Lacrosse or other wired wind gauge instead?
well Since we don’t know what sensors you have exactly I don’t think we can help much. Basically you would need an arduino, ethernet board, and then data sheets on the sensors you have to get started.
I’d just like some kind soul to show how to send some text down the I2C and extract it on the other end. Uno to Uno.
