This paper explains the design and implementation of smart socket energy monitor using the widely used microcontroller Arduino, LCD Display with capability of monitoring via web and application. Nowadays as electric utilities used electric meters installed at customer premises to measure energy consumption for billing purpose; demand for accurate meter reading is sought after. One of the ways in which today's energy problems can be overcome through the reduction of energy consumption in electrical household items. This has increased the emphasis on the need for accurate and economical measurement of energy methods. Energy Meter (E-MON) is used to monitor the usage of energy continuously while the load is connected to the socket. Major components used in this project are Arduino (UNO R3) board, SCT-013-00 current sensor,voltage sensor unit, LCD Display and Module Wi-Fi. In this project SCT-013-00 is used to detect the current and voltage sensor unit is used to detect voltage that goes through the load and socket. Arduino (UNO R3) will detect the input from current and voltage sensor while LCD will display the consumption of load in Voltage (V), Ampere (A) and Volt-Amps (W). This paper explains the process of design implementation and scale prototype and the challenges it faces in monitoring the value via IoT platform.
