ABSTRACT

The idea of informing the host about a visitor at the door started much before the electrical bell was invented until this modern world that bells based on smart technologies that made easy human life. The framework of ultrasonic doorbell systems with smart object detection and distance measuring using Arduino Rev.3 is an access system that automatically sense and indicate the presence of guests and rings the bell. An ultrasonic transducer that converts the Electrical power into ultrasonic sound waves and vice versa plays important role in generating and transmitting a high frequency sound waves to detect a guest and receive reflected or response wave back to terminal in Arduino board then ATmega328 Microcontroller that take decisions processes the signal wave also calculates the distance of the person detected, then shows response to the LCD display and generate a signal to activate the output terminal connecting to Piezo buzzer in order to make alarm when there is an guest arrives. The success  rate of measures implemented indicates accomplishments we have made during our findings also designing, coding and implementing using software simulation and connecting hardware components.

CHAPTER ONE

1.0                                                         INTRODUCTION

1.1                                         BACKGROUND OF THE PROJECT
The history of the doorbell is a long one, starting from the early 19th century and advancing with the times. These days, doorbells are everywhere! They are used for practical visitor-announcement needs, along with security and safety. They can also set a mood or deliver a carefully planned first impression that the home or business owner might want to express.
The practice of informing the host about a visitor at the door started much before the electrical bell was invented. Door knockers were in vogue. The door knocker which is still found in medieval castles or homes with vintage designs has a part attached to the door and is connected to another part by a hinge. It can be lifted up and used to strike the door making a wooden ‘knock sound’ or a metal clang. Not very ornate or audible. The other common type of doorbell used in those days was a string attached to a large bell (something like a school bell). It took a fair amount of effort to ring those bells continually until the host eventually was informed.

The main objective of this project is to develop and build an integrated smart home automation system using IC, microcontroller technologies that is obtained from the market that provide cheap budget service compared to the budget of the conventional doorbell systems.

1.2                                                  PROBLEM STATEMENT
Conventionally, door bell is activated once the visitor approaches the door of the host by making contact / pressing the switch at the door, and this gives the visitor stress when locating the switch most especially at night when everywhere is covered with darkness. However, this device came into existence to overcome the problem of searching for the switch before a door alarm is rung. This device rings an alarm once the visitor approaches the door from a set distance using ultrasonic sensor.

1.2                                             OBJECTIVE OF THE PROJECT
The objective of this work is to design a device will automatically sense the presence of a visitor from a distance and then rings the doorbell without making contact or pressing the door bell switch. This device was built around a arduino microcontroller - which is the heart of the circuit and ultrasonic sensor.

1.3                                         SIGNIFICANCE OF THE PROJECT
This circuit is used to detect the person and then if the person is detected, the door bell is automatically turned ON when the person is in-front of the door. They are used for practical visitor-announcement needs, along with security and safety.

1.4                                              PURPOSE OF THE PROJECT
The purpose of this invention is to save the visitor’s time and labour of searching for the door bell before the occupant of the house is informed of his or her visitor’s presence.

1.5                                               BENEFIT OF THE PROJECT
The benefits of choosing this choosing this topic are:

  • Saves time for searching door bell
  • Save electricity
  •  Enhance security
  • Save manpower

1.6                                         APPLICATIONS OF THE PROJECT

They are used for practical visitor-announcement needs, along with security and safety

1.7                                            LIMITATION OF THE PROJECT

The ultrasonic sensor is mounted where it cannot be easily access by the visitor or an intruder.

1.8                                                        METHODOLOGY
A lot of design research was carried out on door bell. Data books were consulted to make the most suitable choice of components at the most reasonable cost. After the design, a market survey was conducted and some components used in the design were not obtainable in the market. Hence, alternative components had to be used and the circuit redesigned. The subsequent stage involves physically realizing the design work, constructing and packaging the entire circuitry on the frame. Finally, he work was given a fine finish and tested.

1.9                                        PROJECT WORK ORGANISATION
The various stages involved in the development of this project have been properly put into five chapters to enhance comprehensive and concise reading. In this project thesis, the project is organized sequentially as follows:
