Design and implementation of a microcontroller based automatic door and vistors counter

Abstract

The implementation of a Microcontroller based automatic door control with visitor counter will lead to vast improvement on electronic security designs. Nevertheless, for a system with large volume of movement with little or no security consciousness, a door system to fit the system without unnecessary delay in the free flow of movement usually tends to pose a problem. Usually, in this kind of scenario, an automatic door system with a means of detecting incoming traffic so as to open the door as required, thus the design and operational principles of a microcontroller based automatic door with visitor counter. The design is made of sensors that detect human presence, a dynamic display unit that displays different messages at specific time, the H-bridge driver IC controls the movement of the motor attached to the door. The whole system is controlled by an 8051microcontroller (89s51).
