Abstract

Increase of consumption of electricity due to this High-Tech Era, energy saving become very important as power generation still highly depending on non-renewable energy. The only electricity usage measurement tool installed in everyone house which is electric meter only capable of displaying cumulative energy consumption. This conventional type of electric meter causes people clueless about their electricity consumption as it is difficult to track and determine which electrical appliances contribute to that amount of electricity consumption. Therefore, in this project Smart Electric Meter System (SEMS) is designed to ease the process of monitoring the power consumption of electrical appliances and manage their appliances. The SEMS consists of Smart Electric Meter (SEM) that monitor the electricity usage of all the load at home and Smart Electric Plug (SEP) to monitor single electrical appliances. The main component of this project is components that are widely available in market such as ESP 8266, PZEM004T, Real Time Clock Module DS3231, Solid-state Relay, and OLED display. In this project, experiment is done by using incandescent bulb and ballast as load to test the accuracy of voltage and current measurement of SEM and SEP by comparing it to Flukes 317 True RMS Clamp Meter. The error for voltage measurement of SEM is ranging between 0.177%-0.279% and error for current measurement is ranging from 4.274% to 6.279%. For SEP the error of voltage measurement is between 0.045% and 0.124% while error of current measurement is between 4.167% and 7.477%. The SEP in this project also provide energy management feature which been tested in this research that it is capable of saving 57.35% of electricity and 45.86% of cost for electricity when compared to load that connected to a normal power plug.
