1. Executive Summary
The objective of the project was to create a circuit with an 8051 microcontroller that senses when an object passed through an infrared receiver’s receive path to automatically turn on lights and count how many times the receive path was blocked. 2. Introduction
Digital visitor counter is a reliable circuit that takes over the task of counting number of Persons/ Visitors in the Room very accurately. When somebody enters into the Room then the Counter is Incremented by one. The total number of Persons inside the Room is displayed on the seven segment display module. The microcontroller does the above job it receives the signals from the sensors, and this signals operated under the control of software which is stored in ROM.
It can be used to count the number of persons entering a hall in the up mode at entrance gate. In the down mode, it can count the number of persons leaving the hall by decrementing the count at exit gate. It can also be used at gates of parking areas and other public places.
This circuit divided in three parts: sensor, controller and counter display. The sensor would observe an interruption and provide an input to the controller which would run the counter in up/down mode depending upon the selector setting. The same count is displayed on a set of 7-segment displays through the controller.
This project we will create counter system for apply. The total number of object is displayed on the seven segment display. The system is fully controlled
