know of a component to read voltage and amperage?

Hi everyone!

i just want to ask if any of you know where I can buy component parts that I can use with my arduino to measure up to 250vac, as well as amperage.

Thanks!

There are lots of demonstrations/tutorials at the OpenEnergyMonitor site.

Used a KWH meter in a project once - Arduino Playground - EEM12L-32AKWhMonitoring - worked very well.
