Android-based application for real time energy monitoring of domestic electricity

The electricity demand keeps on increasing year by year. In Malaysia, energy consumption has increased rapidly from an average of 5% in 1980s and 12% in 2009. Due to this increasing trend, government has encouraged users to reduce their electricity consumption. One of the way is by introducing the smart meter as a solution, where the smart meter device is used to display the total of energy consumption by users. In this context, we have developed an online-based energy smart monitoring system for domestic electricity consumption. This system offers a beneficial feature, where the user is able to monitor which part of a house consumes more power energy than others. In recording the electricity usage, smart meter microcontroller is installed to continually measure data for different areas of a house. The captured electricity usage data is uploaded by the microcontroller to an online database, which can then be viewed by users on their Android devices. Through this monitoring system, the objectives are achieved such that the users are able to know how much energy are being consumed for a particular area in the house. The Android application provides an interface to show the analysis of electricity consumption for different areas of a house in terms of voltage, current, power consumption and the corresponding pricing for a specified duration.
