This document provides an abstract for a student project that aims to create a microcontroller-based bidirectional visitor counter and home automation system. The system will use an AT89S52 microcontroller to control room lights and accurately count the number of people entering and exiting a room based on signals received from sensors. It will increase the counter value when people enter and decrease it when they leave. The goal is to develop an automatic system that eases complexity and allows monitoring how many people are in a room.

2. ABSTRACT
Title: Bi-Directional Visitor Counter & Home Automation
Objective: The objective of this project is to make a Microcontroller based model to
count number of persons visiting particular room and accordingly light up the room.
Materials & Method: The Project “Bi-directional Visitor Counter and Home
Automation” will be made by using Microcontroller AT89S52 that takes over the task of
controlling the room lights as well as counting number of persons/ visitors in the room very
accurately. The model will receive the signals from the sensors, and this signal will be
operated under the control of software which will be stored in ROM.
Results: This Project will be a real-life model which will have the ability to perform the
task of counting in both direction. Not only it will increase it’s counter when any person
will enter the house but also when any person leaves the house, counter’s value will reduce
considerably.
Conclusion: In today’s world, there is a continuous need for automatic appliances with
the increase in standard of living, there is a sense of urgency for developing circuits that
would ease the complexity of life. Also if at all one wants to know the number of people
present in room so as not to have congestion, this circuit will prove to be helpful.
