Smart energy management for residential buildings based on wireless embedded system

In the thesis, a smart power strip has been developed to save electric power consumption at home. Also, developed power strip allows user to manage power at their home by turning on/off electricity of home appliances. The developed system utilizes wireless power monitoring devices and controls units. The electronic wireless power monitoring devices has been designed to monitor electrical parameter as the current of the household appliances. The developed smart power strip integrates many hardware components, embedded software and application program for access the power strip over internet. XBee module as wireless module has been used to make communications between central control unit and smart power strip. The measured electrical parameters are transmitted to a central controller via the ZigBee node. Raspberry pi card (mini computer) has been configured to play vital role as a web server and coordinator to switch ON/OFF smart strip power and measure power consumption of plugged home appliances that are collected from power sensor using XBee protocol. In addition to, software has been developed using HTML, PHP, Javascript and Phyton to design web page as platform compatible with any internet browser in any smart phone or personal computer. However, our developed system requires static IP number. We have evaluated our design under different conditions. We have found the results are satisfactory.
