Abstract
There is described a system to measure the electrical consumption of a household. This system consists of a network of measuring devices that are attached to wires between electrical appliances and circuit breakers and of a communication and processing unit that receives measurement data from the measuring devices. Low precision sensors based on the Hall effect may be used for obtaining precise measurements of energy consumption by providing a casing for the measuring devices that ensures a fixed, known, and precise alignment with respect to the wire to which it is attached. Low precision sensors based on the Hall effect may also be used by performing a correction calibration of measured data.
