RANCANG BANGUN SIMULASI SISTEM KEAMANAN RUMAH DENGAN PANGGILAN TELEPON MENGGUNAKAN SENSOR PIR

Security is of absolute desired by everyone. In fact many owners abandoned homes burglarized by thieves without being noticed by the owner. For that we need a home security information quickly and effectively so that homeowners can immediately find out if the house will get broken by thieves. Alarm going off and the phone will contact the owner if there are people who enter. Source voltages used in the circuit is provided by the power supply circuit. Power supply circuit to supply the needs of electric current for PIR Sensor, IC LM358, timer, and alarm via relay circuit. Flow system on the tool begins with identifying active PIR sensor infrared light as motion detectors. These sensors will then generate an electrical signal in the form cues. Electrical signal which is a reaction to the response of these sensors will then be directed to the LM358 IC for processing signals generated in order to be more stable. The results of processing these signals will then be directed to the relay circuit that serves to activate the alarm. In a phone call mode as a form of delivering information to homeowners calling process is done by using the function as a multivibrator NE555 timer IC connected to the phone. In this way the home can be monitored remotely so that security can be maintained home. Keywords : PIR Sensor, IC LM 358, NE 55
