Jason has released a new ioBridge project that monitors water usage for his whole house in real-time. The system uses a water meter, an IO-204, and ioBridge data logging services. His first system monitored power usage, sunlight, and temperature which included a live demo mash-up with Google Charts.
On one channel of the IO-204, the water meter is connected to the digital input. On a digital state change, the module sends that data to the ioBridge servers. Included with the free user account is the ability to log two data feeds from your module. In this case, the type of log is a Digital Input Counting Log. Evey count is the equivalent to one gallon of water used. The project is rather interesting and the next step in conservation. Knowing water usage and finding your high water use times will help curb use in the long run. Details on the water meter project can be found on Jason’s blog and Instructables.
