SISTEM OTOMATISASI LISTRIK RUMAH TANGGA MEMPERGUNAKAN SMART STECKER BERBASIS MIKROKONTROLER ATMEGA32A

Abstract

Recently the electrical energy has become a primary need for the community, but their sources have a limited amount so that the excessive electrical energy consumption will result in shortages of electricity. One of ways is a proposal of automation control systems in household electricity with the use of Smart Stecker. The control system is done by connecting a Stecker at electric plugs with a circuit which consist of thyristor, Integrated Circuits and microcontrollers. The entire circuit is set up C-language and the solution is displayed on a Computer using program Microsoft Visual Studio 6.0. This research has produced a tool that its usage can control the current of household appliances such as a bulb by setting the Pulse Width Modulation (PWM) of 25%, 50%, 75% and 100%, so that the result shows the current changes due to the pulse width obtained into the linear regression I = 0.0011 PW+ 0.0007 and the correlation coefficient of 99%. By controlling ON / OFF switch the current household appliances, the circuit achieves the load of 1 Ampere input and produce 220V at output port, but the maximum input load can be given by 8 Amperes. The last function of smart sctecker is to detect the tools ON / OFF switch.
