http://twitter.com/gisvoldhouse now points to a Twitter from various sensors in and around our house.

The starting point is very simple - it just reports (every hour) the temperature and humidity in our garage, so not much to get exited by/

But it is the start of a architecture to gather and control information from various sensors and controllers around the house - and a test of this infrastructure which consists of a number of Ethernet connected Arduino boards with sensors and control devices attached to them. A simple webserver runs on the Arduinos, and software written to interrogate and set the various ports and sensors run on the Ardunio itself.

They are in turn controlled by web-enabled software written in Ruby running on a Mac Mini (which is also our house server for all kinds of other purposes), which uses HTTP (as the Arduino has a small webserver) to communicate between the machines. And this sends some of the results out over Twitter.

Wait for more sensible data to appear.
