Wi-Fi Based Smart Energy Meter

Home automation is fast popularity nowadays.An automatic remote meter-reading system based on      Wi-Fi is presented in this paper can be considered as a part of home automation. The Energy data collection system is a very important step and part in the research of energy visualization and analysis. Through this system, consumer can easily know their electricity usage at any instance and their behavior to reduce their energy consumption and costs.  Wi-Fi based smart energy meter system is presented in this paper is in terms of reduces errors, absence of consumer while taking reading etc. There are many possibilities to collection of energy data. The main aim of the paper is to develop remote energy measurement system using Raspberry pi board consisting ARM11 processor and use sensors. Sensors data are stored in Raspberry pi and sends related data over Wi-Fi through the home’s wireless router to the base station. Furthermore, display all data such as energy consumption (Power), unit or other sensors detail on LCD.The base station collects the energy data, stores it in database and uses it for energy visualization, calculation and analysis using GUI application on Qt Creator.The design of GUI for embedded systems is different from that of traditional data computing, which often handles mouse or keyboard events to complete a specific calculation, while for embedded systems the events are caused by external devices.
