power monitoring
Use a clamp meter adapter for multimeter.It uses a hall effect sensor
and a ferro magnetic clamp to concentrate the flux. Then use an A/D to
take measurements.

(actual) power will need to include the phase relationship between
the current and voltage waveforms. Power companies do this.
Industrial wattmeters are more complex than the household meters.

>Hi Nick -
This is by no means a Stamp solution, but you may want to see what's
available from E-Mon. They have a nice line of meters for industrial and
residential power usage.
Hope this gives you some ideas.

Bruce Bates

I am attempting to use a basic stamp to monitor, log and display the
power consumption of an industrial building. I need to find a sensor I can
use to measure power usage (actual). Idealy the sensor/monitor would be
non-invasive, alloing for installation without taking down the whole
building. Has anyone done anything like this or does anyone have any ideas?
Thanks,
Nick H
