Aim of the project:
The main objective of this project is to develop an Automatic
Door opening system using IR sensors which will reduce the
need of manual labor.
Methodology:
According to our project requirements, the following modules
are essential.
· Power supply
· Microcontroller
· Stepper Motor
· IR sensors
Significance and applications:
Automatic door opening systems using IR sensors plays a very
important role in domestic applications. The elimination of
manual supervision adds up as an additional advantage for its
usage. Its significance can be proved by considering the
following specialties of kit designed by us
· Reliability: Reliability is one such factor that every
electrical system should have in order to render its
services without malfunctioning over along period of
time. We have designed our kit using AT89C52 micro
controller which is itself very reliable and also operates
very efficiently under normal condition
Organization of the report:
The report totally consists of seven chapters - Chapter 1 gives the
introduction to the project, Chapter 2 provides an overview of the project
with the help of a block diagram, Chapter 3 gives a note of embedded
systems usage, Chapter 4 explains about the circuitry and the
interconnections of the project, Chapter 5 explains in detail about the
components used in our project, chapter 6 provides a compact project
description, chapter 7 makes use of a flowchart , and then followed by the
conclusion.
INTRODUCTION TO EMBEDDED SYSTEM
An Embedded system is a special-purpose computer system
designed to perform one or a few dedicated functions, sometimes with
real time computing constraints. it is usually embedded as a part of a
complete device including hardware and mechanical parts. Since the
embedded system is dedicated to few specific tasks, design engineers
can optimize it, reducing the size and the cost of the product or
increasing the reliability and performance.
For example, handheld computers share some elements with
embedded system= such as the operating systems and microprocessors
which power them –but are not truly embedded system, because they
allow different applications to be loaded and peripherals to be
connected. The program is written to the system memory in this case
rather than being loaded into the RAM, as programs on a personal
computer are.
The main purpose of the microprocessors are simplify the
system design and improve flexibility. In the embedded systems, the
software is often stored in a read only memory (RAM) chip.Embedded
systems provide several major functions including monitoring of the
analog environment by reading data from sensors and controlling
actuators.
MICROPROCESSOR AND MICROCONTROLLER
Microprocessors and microcontrollers are used in embedded
system products. An embedded product uses a microprocessor (or
microcontroller) to do one task and one task only.
Microprocessor as the term come to be known is a general
purpose digital computer central processing unit. Although popularly
known as a "computer on chip", the microprocessor is in no sense a
complete digital computer.
8051 MICROCONTROLLER
8051 Architecture
The generic 8051 architecture contains two separate buses for
both program and data. So, it has two distinctive memory spaces of
64× 8 size for both programmed and data. It is based on an 8-bit CPU
with an 8-bit accumulator and another 8-bit B register as main
processing blocks. Other portions of the architecture include few 8 bit
registers and 8 bit memory locations.
