Monitor household gas use over the Internet with Arduino

Technologist Richard Parker made a device to monitor electricity consumption which published the data over the Internet via cosm (Pachube), and he now returns with a method of measuring the gas consumption as well. Using an Ethernet-enabled Arduino board, some external circuitry and a photo reflector his system can detect the rotation of the flow wheel in the gas meter, and then determine the volume that has been used. At which point the data can then be processed, broadcast and so on. The only catch is that gas meters can vary wildly, for example ours has the small plastic rotating needle:

When putting together your next Internet-enabled Arduino project – save time, space and money with the Freetronics EtherTen. Apart from being fully Arduino Uno-compatible, it has onboard Ethernet, microSD socket, full USB interface (so you don’t need a costly FTDI cable just to upload a sketch!) and supports optional Power-over-Ethernet.
