Abstract
A group of sensors use power line communication (PLC) technology to collect power usage information and enable power management and control, as well as provide local area networking. The sensors include an intelligent master sensor and one or more slave devices, such as a communication and power management sensor and a power control switch sensor. The master collects and compiles power usage data from the slaves and communicates this data via the web or other communication means to the outside world. The master also receives and distributes instructions for controlling power usage via associated switches in the home or office. These sensors provide integrated sensing and control of home power usage and power management and establish a LAN that has communication capability and that supports streaming media delivery.
