SISTEM KEAMANAN RUANGAN MENGGUNAKAN SENSOR PASSIVE INFRA RED (PIR) KC7783R DENGAN MIKROKONTROLER AT89S51

Abstract

System of security use microcontroller AT89S51 has been designed and realized. This Appliance can be exploited for building security system by a company or luxuarious house security. System consisted of hardware and the software. The hadware consist of microcontroller AT89S51, network PIR sensor KC7783R and buzzer. The microcontroller’s software was built on assembly language. Alarm will be active every time of human being movement. This system work after PIR sensor KC7783R detect the human being movement, hence PIR sensor KC7783R will send the sinyal to mikrokontroler, then mikrokontroler fire the alarm deputized by buzzer. This system have been realized and can be made a security system by sounding alarm automatically. If anyone who is on the heels of undesirable moment, so alarm will sound.
