RANCANG BANGUN SISTEM KEAMANAN RUMAH YANG TERHUBUNG DENGAN HANDPHONE MENGGUNAKAN SENSOR LDR BERBASIS MIKROKONTROLER ATMEGA8535

Abstract

Design and realisation of house security system based on Atmega 8535 microcontroler had been done. This device can be used as a house security system or company building. The hard ware consists of 2 piece of LDR (Ligth Dependent Resistor) sensor driver function as a motion sensor and a driver relay connected with an alarm. Data processing system uses Atmega 8535 Microcontroller IC. This hard ware connected with handphone,Siemens SL 45, fuction as a server. It’s show, LDR sensor will give an data input to microcontroller if LDR sensor is passed by ancertain object. And then, microcontroller will give data to handphone server in the form of message that will be sent automatically to house owner’s handphone and activated the alarm simultaneously.
