DESIGN AND CONSTRUCTION OF AN AUTOMATED DOOR WITH COUNTING SYSTEM

Abstract

This project is design and construction of an automated door with counting system, it is used to open and close a door as the first person approaches the door and last person leaves respectively. The system also display the number of people entering and the number of people leaving as well as the number of people remaining in the building. It has also both logistic and security application. For logistics, it can be used to know the number of people in a conference, seminar or other formal gathering so that the number of conference materials (brochures, speeches, programmes of events, refreshments eto.) to be produced can be known. For the security aspect, it can be used in banks, supermarkets, museums, park and resort center to ensure that no one is locked· in (either by mistake or intentionally) at closing time. The door has LOR( light dependence resistor), such that a light beam is broken each time a person passes through the door and the signal is sent to a digital control circuit which aids the counting and the automating of the door.
