Low-cost non-intrusive residential energy monitoring system

This paper explains the implementation of a low cost, non-intrusive home energy monitoring system. The design implementation of the proof of concept employs open-source hardware architecture using Arduino and off-the-shelf sensors which lends itself to mass production, low cost and easy maintenance. This system is intended to service rural and low income urban consumers who will not be able to afford existing sophisticated and expensive home automation systems. A device identification module (DIM) that recognizes the devices in use at every room is implemented. The energy usage is continuously monitored and the user is notified of his consumption over a twenty four hour period. As many of the intended users are possible first time energy consumers, the energy monitoring system will inculcate a sense of energy consciousness and ensure grass root level sustainability. The energy consumption data is logged in the system and can be used by the utility service provider (USP) for future system planning, optimization and demand side management. The proof of concept developed and tested under laboratory conditions costs under USD 11 and will reduce further on commercialization.
