Design and Implementation of a Module Door Lock System Based on Java Language and raspberry pi Board

ABSTRACT Identification technique using Bluetooth of a personal smart device is very useful and applicable method. in this proposed system, this technique used in order to control an electromagnetic lock. The proposed system consist of two main sides which are hardware and software. Hardware side consists of smart device, Raspberry pi board, Relays and electrical lock. the software side consist of Java language for program the application in smart device and python language for programing Raspberry pi. When user reach around the reading range area of the lock system, he can open or close the lock by just send a command using application in his device. so this proposed system can be used in state of all the keys of a user. So it is easy and useful Keywords: Door lock, raspberry pi, Java and Bluetooth.
