I did a fair bit of research before setting out on this. The following is a partial list of sites that I got ideas from:
- Temperature Logger (somebody else's)
- Slashdot Beer Brewing Story
- Quozl's Temperature Sensor Project
- Monitoring Natural Gas Usage (analog)
What's Next? I would like to find an inexpensive way to montior electrical power usage. Something like what this guy did would be cool - if it were not for the multi-thousand dollar price tag. Suggestions are welcome.
This bwired fellow seems to have taken it to a whole different level. I can't do it exactly like this, since I still have an Analog meter. Another similar one, again with a digital meter. There was a page at seanadams.com (archived version) where a circuit was hooked up with an IR emitter/receiver rigged up to his analog meter, but it seems to be offline now. Also, there is another flashing LED reader (http://phk.freebsd.dk/Eldims/)./p>
