DIY Amp Hour Meter
Ever wanted to see how much electricity your next project is consuming? Look no further; this Instructable will guide you about how you can, too, make a device to monitor the same.
This project was developed by Steve Spence of Arduinotronics with input from forum members at the Yahoo Group – Arduino Home and The Arduino Forum.
“There’s a couple of commercial products that can do this, but not with the flexibility I wanted. I designed an Arduino micro-controller based solution that is very extensible. Right now it monitors the above values of attached gear, and I’m thinking about adding web monitoring and an SD Card for data collection.”

I have built something similar but I follow my houses overall electricity use (and oil use and other things).
