Smart Energy Meter based on Arduino and Internet of Things

Abstract

Abstract Energy meter is a measuring instrument to calculate the amound of electric energy consumed by an electrically powered device. The energy metering which measure line voltage, current, and calculating active power can be used to increase usage efficiency of electricity. This paper presets a system which provide real time energy meter reading using ACS712 as current sensor, ZMPT101B as voltage sensor, arduino and an IoT server. The energy meter can display consumed energy in kWh and electricity bills to be paid. system’s user interface is in Android. the error in current measurement is less than 2 % and error for peak to peak voltage measurement is 4 %. A notification for the amount of electricity energy usage or electricity cost can be generated for user to be displayed.
