INTRODUCTION
The industrial batch counter is an electronic and
electrical device that handles the counting and controls the flow of
individuals using an automated slide door that allows access only when the
administrator permits. The technique involved in the design is a simple sensor
unit that opens and closes the door when someone obstructs the light path.
These parameters can be used to determine when someone has moved in or out of
the conference hall (for instance). The light sensing type involves monitoring
the unit with photon or optical devices; this consists of the encoder
(transmission path or the source of energy) and the decoder (receiver unit that
converts the light intensity to electrical signal). An LED emitter, combined
with a photo detector (Light Dependent Resistor, photo transistor or infrared
sensing diode) in proximity, form a very useful object called opto-coupler or
opto-isolator. When the opto coupler is obstructed, the door opens and the
display shows an increase or decrease of individuals in the room (depending on
the path followed). This project report creates a greater picture of the
industrial batch counter.

THE AIM AND OBJECTIVES OF THE PROJECT
The aim of this project is to demonstrate a smart device
that counts the number of people inside a conference hall; and prevents people
from entering once the room has reached its capacity.
1.5
JUSTIFICATION OF THE PROJECT
The need for counting the number of persons inside the conference hall is
for statistical record, which will help the conference hall management take a
proper account of people; and as well, control the conference hall capacity
from being over populated.
1.6
THE SCOPE OF THE PROJECT
This project covers the
features of the capacity monitor, the hardware description, the use of
transistor-transistor logic and microcontroller, how the system works and its
applications.
1.4
THE PROJECT REPORT ORGANIZATION
This project report is organized
into five chapters. The first chapter covers the introduction, aim scope and
justification of the project. The second chapter talks about the technology
behind the project, the description of the microcontroller, as well as the
working principle of the project. Chapter three covers the methodology of the
project. Chapter four discusses the designing and construction of the project,
as well as other components used in designing this project. Chapter four also talks
about the testing of the individual components and packaging of the project.
And lastly, chapter five summarizes and concludes the project.
