A smart monitoring and control system for the household electric power usage

This article builds a smart monitoring and control system for the household electric power usage. The system presents the complete picture of current usage and projected cost of home appliance in a graphical display. It uses wireless communication to monitor energy saving and safety use. This can provide the elder a safe and energy-saving environment and service for daily life. The system integrates power parameters measurements and household appliance control into a household power usage system. It is done by an electric energy detection chip to measure electric parameters of all outlets for digitizing electric signal. Then the signal is processed by the microprocessor for analysis and unified output format. The processed measurements are sent by the ZigBee wireless module. The controlling computer will compute the received parameters to control the state of outlets. A user interface is designed from the user's perspective.
