Abstract

This project presents the Design and Implementation of Access control System using PIC Microcontroller. The design is coded and implemented using MikroC language for the purpose of implementation inside the PIC Microcontroller. This design consists of a remote sensor which is used to detect the feedback signal. Automatic door system is used as an industrial application for the access control system where presented by this paper. The automatic door system model is designed and implemented with PIC-16F877A micro controller, laser sensor and DC motor and custom designed structure for its automatic door system. MikroC programmer is used to test the design codes, and Protus Simulation program is used for the purpose of simulation for the schematic of the design. The design needs maximum clock frequency of 4 MHz. Therefore, the proposed design will be able to cover a wide range of applications with a high sampling rate. Enhancements are made for the design to decrees the memory size in order to get fast execution time. The used ROM is 600 Byte (7.3%) from 8191 Byte and the used RAM is 93 Byte (26%) from 368 Byte of the memory size of PIC Microcontroller. Experimental results show a fast execution time for detecting the interrupts of the remote sensor. Therefore, the proposed Access Control System can be used with different industrial applications. It is very convenient system for consumers and has extensible and flexible characteristics. It can also be used for home doors with additional sensor devices.
