Kontroler Alarm Rumah VIA SMS Menggunakan Microcontroller AT89S51 dan Handphone Nokia 6210 didukung Oleh Basic Compiler

Abstrak

A house security system is one of the applications of  microcontroller chip benefit. This system can reduce the usage of human power to control a house security eventhough the owner is not in the house.  This research was done  by designing, creating and implementing all system components. The components are microcontroller as a process controller, basic compiler as programming language, limit switch as input device to system, barlet and buzzer whitch are used as SMS sending process activation, and the last is Nokia 6210 used for sending SMS to the house owner’s phone. This research showed that the tools function properly and can be developed in larger scale. This research is aimed  to develop Microcontroller AT89S51 application as a house security controller.
