Operation Cold House

Published on Sunday, June 14, 2009


My house is cold. I want to start playing with simple electronics before starting Operation Field, so have created Operation Cold House.

This is just simply sticking a temperature sensor onto an Arduino, linking that up to my little home "server", and uploading that to my website. I'll display some nifty graphs, too, and link it to Pachube. Stay tuned.

Update: Complete! The proof is in the pudding. I now have a personal website from home (sorry, not public) that displays the daily and weekly temperature at home. The process is basically like this: my little Arduino gathers the temperature, and is polled every minute with a python script via cron. This script then sticks the time and temperature into MySQL. It also exports the temperature to Pachube. Every 30m I have a script that queries MySQL and uses Google's Chart's API to graph the temperature. Looks great, I'll post a graph soon.
