ABSTRACT

Hafurda Yudhistira Yoga Firmansyah, Computer Engineering Program, Department of Information Technology, Polytechnic of Jember, September 2, 2014. This final project will be made a Safety Door System Using PIR Sensor and Password Based Microcontroller Atmega 32. Commission Advisor, Chairman: Elly Antika, ST, M. Kom

Working Principle of this door safety system is to process the input signals of infra red from objects moving through PIR Sensor and Password which being interfaced to mikrokontroler Atmega 32 for identification process. If process identifies compatible, then the microcontroller will drive the automatic lock to open, but if the wrong password is entered, the microcontroller will sound the loudspeaker until the password is entered correctly.

Data Entered in the from of infra red from objects moving through the PIR Sensor and Password typed by the user. By microcontroller, the data would processed. Microcontroller does identification of automatic door lock to make a move or not. If identification user through PIR Sensor and Password has compatible, automatic door lock will be moved by the driver as according to information received from microcontroller. Automatically lock the movement process will run until the interval of time that has been set at the beginning of the use of these tools.
