Happy viewing!!!
The project is on an automatic security door alarm system used in places like shopping malls, hotels and theatres.This project proposes a system of automatic security sensing any body movement object near the door. This is achieved with help of a PIR (Passive Infrared) sensor. A live body generally emits infrared energy which is sensed by the PIR sensor from a considerable distance. This sensing signal is fed to an integrated circuit to trigger a buzzer.
When a body approaches within the operating range of the sensor, it sends a logical command through an alarm indicating that someone is approaching the door. If there is no further movement within the PIR operating range.

1.0 INTRODUCTION
1.1 BACKGROUND OF THE STUDY
The need for having home protection has always been there. But in the recent times, considering a dramatic rise in petty crimes like robbery and theft, the need has been more strongly felt to have a fool proof protection of the belongings and the family members. Home security has come a long way in the last few decades. It was in the hands of a guard who manually provided surveillance during nights in the earlier days, but it was not fool proof as it was only normal for him to have momentary lapse of concentration.
The guard was also susceptible to sleep at times. It was then that home alarm system based upon electronic circuits were developed which proved to be highly reliable and were appreciated by the people as they were relieved from constant monitoring of their homes.
A house door alarm is a signaling device typically placed near an entry door to a building. This device is a motion based automatic door bell that rings a bell when a visitor approaches the sensor, alerting the occupant to the presence of the visitor.
A digital door alarm system is one of the home door alarm which is also called motion detector: The most common single-technology motion detecting sensor uses an ultrasonic sensor to detect movement of object, such as a person walking near the door. It is most effective in detecting when the heat mass moves across its field of vision.
Today we are adding one more Security Alarm in our list which is based on Ultrasonic Sensor and LCD which is the main aim of this work.
1.2 PROBLEM STATEMENT
The need for having a constant home protection has always been there. But in the recent times, considering a dramatic rise in petty crimes like robbery and theft, the need has been more strongly felt to have a fool proof protection of the belongings and the family members. Home security has come a long way in the last few decades. It was in the hands of a guard who manually provided surveillance during nights in the earlier days, but it was not fool proof as it was only normal for him to have momentary lapse of concentration. This device brought solution to this need. It ensures adequate protection against intruders. This study also overcome the difficulty experienced by visitors in pressing a door alarm, in most especially when the visitor is disabled and could not have access to the location of the doorbell.
1.3 AIM AND OBJECTIVES OF THE STUDY
The main aim of this work is to design a device that will trigger a door alarm when sensing visitor’s body movement near the door. The objectives of the study are:
- To the build the system prototype
- To overcome the difficulty in pressing a door bell
- To provide an adequate security in our homes
1.4 SCOPE OF THE STUDY
The scope of this study covers building an arduino based digital door alarm using ultrasonic sensor. This Arduino Controlled Door alarm can be installed near the door to detect the presence of anybody at the door. Whenever somebody comes in the range of Ultrasonic sensor, buzzer starts beeping. You can adjust the sensor detection range according to your door.
1.5 SIGNIFICANCE OF THE STUDY
This study will serve as a means of providing adequate security in our homes and provide a good knowledge of how arduino can be interfaced with ultrasonic sensor.
1.6 METHODOLOGY
To achieve the aim and objectives of this work, the following are the steps involved:
- Study of the previous work on the project so as to improve it efficiency.
- Draw a block diagram.
- Test for continuity of components and devices,
- Design of the device was carried out.
- Studying of various component used in circuit.
- Construction of the circuit was carried out. The construction of this project includes the placing of components on Vero boards, soldering and connection of components,
- Finally, the whole device was cased and final test was carried out.
PLAN OF THE STUDY
This project work is basically divided into five (5) chapters:
CHAPTER ONE: Takes on the introduction of the subject matter. If consists of the objectives, significance and problem statement of the study.
CHAPTER TWO: This is the literature review this entails the works that had been done on this particular topic which was done by other researchers.
CHAPTER THREE: Will talk about the Method that the researcher adopted in getting necessary materials or information that will facilitate the success of the research work.

CHAPTER FIVE: Brings everything to conclusion the researcher does his summary and give necessary recommendation where needed.
CHAPTER FIVE
5.1 SUMMARY
The invention relates to a method for detecting the approach of a person on the outside of a closed door and producing a pleasing tone on the inside of the door when such an approach is detected, adaptable to function as an automatic doorbell.
The method involves the use of a microwave proximity sensor capable of detecting the approach of a person within approximately six feet, and able to differentiate between a person on one side and a person on the other side of the sensor, and a tone generator connected to the sensor such that an audible tone is generated when the approach of a person on one side of the sensor is detected, but not when the approach is made from the other side.
The primary object of the invention is to provide a means for detecting the approach of a person on the outside of a door and for generating a pleasing tone when such an approach is detected.
A further object is to allow said means to be housed in a single small container, self contained and battery operated, eliminating the need for the installation of any components outside of the door, and enabling said means to be installed without any wiring whatsoever.
A further object is to enable said means to distinguish between the approach of a person on the inside of the door and an approach made on the outside, such that a tone is generated only when the door is approached from the outside, but not when the door is approached or opened from the inside.
A further object is to allow said means to operate off batteries by reducing the power drain to a very low level.
A further object is to enable said means to produce a pleasing tone resembling the "bong" produced by some mechanical doorbells.
5.2 CONCLUSION
This project has been designed. Door alarms are a common convenience in homes; giving visitors a way of announcing their presence and preventing residents from missing deliveries or guests. Door alarm are simple pieces of home equipment that let you know a visitor has arrived. They're useful if you are too far from the front door to hear someone knocking and preventing residents from missing deliveries or guests. Door alarms are simple pieces of home equipment that let you know a visitor has arrived. They're useful if you are too far from the front door to hear someone knocking.
5.3 RECOMMENDATION
