Smart Household Socket with Power Monitoring & Control Using Android Application

This paper presents the idea of replacing old commercial wall sockets with smart sockets that can wirelessly control the operation of appliances using an Android application. The proposed design uses ATmega 328 microcontroller, Arduino mega 2560 board, current-sensor and HC05 transceiver bluetooth module. Each smart socket can handle 25A load, it calculates the total cost of power consumption and allows users to control appliances up to a 20-meters distance. The calculation of real power, voltage and current were considered in discrete time and programmed in Android Studio using Java. Actual tests were carried out using 12 different resistive and inductive loads. A parameter comparative analysis was made between the proposed system and an existing energy logger.
