WIRELESS SENSOR NETWORK FOR MEASUREMENT OF ELECTRICAL ENERGY CONSUMPTION
First Claim
1. A system for measuring electricity consumption of an environment having a plurality of electrical appliances, the system comprising:
- a plurality of measuring devices for connection to a wire between one of the plurality of electrical appliances and one of a plurality of corresponding circuit breakers, each one of the measuring devices comprising;
a Hall effect sensor configured to measure a current flowing through the wire; and
a casing defining an enclosure for receiving the Hall effect sensor and comprising an attachment member for engaging with the wire and fixing a position of the Hall effect sensor with respect to the wire to a known relative position; and
a communication and processing unit in communication with the measuring devices and configured for receiving individual consumption measurement data representative of the electricity consumption of the plurality of electrical appliances.

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.
