ABSTRACT
We present the design, development, and evaluation of an
end-user installable, whole house power consumption
sensing system capable of gathering accurate real-time
power use that does not require installing a current
transformer around the electrical feeds in a home. Rather,
our sensor system offers contactless operation by simply
placing it on the outside of the breaker panel in a home.
Although there are a number of existing commercial
systems for gathering energy use in a home, almost none
