Design And Construction Of Sound Sensor Controlled Room Automation System With Burglary Alarm Using Arduino

ABSTRACT

The concept of Home Automation is gaining popularity as it helps in reducing human effort and errors and thus increasing the efficiency. With the help of Home Automation system, we can control different appliances like lights, fans, TV, AC etc. Additionally, a home automation system can also provide other features like security, alarms, emergency systems etc. can be integrated. There are many types of Home Automation Systems like Bluetooth Controlled, Internet Controlled, RF Controlled, Remote Controlled (IR Remote) etc. Each type has its own advantages and disadvantages. In this project, we have designed a sound / Voice Activated Home Automation system, where different appliances are controlled by sending a Voice Command.

The sound or Voice Activated Home Automation project is implemented using Arduino UNO, Bluetooth and a smart pho

1.0                                          INTRODUCTION

1.1                          BACKGROUND OF THE PROJECT

Home automation is one of the major growing industries that can change the way people live. Some of these home automation systems target those seeking luxury and sophisticated home automation platforms; others target those with special needs like the elderly and the disabled. Typical wireless home automation system allows one to control house hold appliances from a centralized control unit which is wireless. These appliances usually have to be specially designed to be compatible with each other and with the control unit for most commercially available home automation systems. The developed system can be integrated as a single portable unit and allows one to wirelessly control lights, fans, air conditioners, television sets, security cameras, electronic doors, computer systems, audio/visual equipment’s etc. and turn ON or OFF any appliance that is plugged into a wall outlet, get the status of different sensors and take decision accordingly. The system is portable and constructed in a way that is easy to install, configure, run, and maintain. The perfect user interface still does not exist at present and to build a good interface requires knowledge of both sociology and technology fields. According to major companies that are involved in speech recognition researches, voice will be the primary interface between humans and machines in the near future. The problem lies with the situation of the elderly or disabled people, who cannot usually help themselves to move around, and might require external assistance. People who live alone might also need a helping hand at home. Therefore a voice controlled home automation system is designed, so that the users can perform certain tasks by just the use of their voices, moreover, the system is designed to have a hand-held device(remote) so that the user can easily speak their commands, otherwise they would have to walk over to the microphone to speak. Having a remote will make the system more user-friendly and portable.

1.2                          PROBLEM STATEMENT

In the last decade, all home appliances are manually operated, and this sometimes exposes the user to the risk of electric shock, and which also cause time wastage and also involves labour, but today the story has challenge which brought solutions to these problems by controlling home appliances wirelessly. Here, the project is based on sound sensor based home automation system via Bluetooth control using arduino, which could help to save energy like electricity and lots of physical strength. It could be secure, flexible, help to prevent power and more accurate outcomes. Most of houses in the cities of the developed countries now using bluetooth based home automation system to prevent energy and ensure adequate safety.

1.3                            AIM OF THE PROJECT

The aim of this project is to enable users to remotely control their home appliances and systems using voice or sound command via cell phone Bluetooth and also to use the same system to detect intruder.

1.4                             SIGNIFICANCE OF THE STUDY

home automation provides the facility of passing information and commands among different installed devices and systems. Such facility and control not only provide better control locally and remotely but also supports special needs, particularly services that support the elderly. Smart home technology also greatly improves the usability and functionality of any home. It also allows to potentially reducing power consumption by preventing occurrences such as lighting and air conditioning being left on longer than necessary. A smart Home Automation system allows saving money and the environment. The burglary alarm attached to this work ensures security against intruders.

1.5                           APPLICATION OF THE PROJECT

This systems provide the facility for monitoring and managing the performance of the home, and offer the choice support to the occupants for available facilities. The varieties of systems are installed in today’s modern home such as central air conditioned and heating, fire and security alarms, and different other devices, such as home theater, televisions, lights etc.

1.6                                  SCOPE OF THE PROJECT

This is a project for a voice controlled home automation system to control appliances with your voice through an Android app. An Arduino Mega board is used for controlling the relay through which an appliance is switched on/off.

The proposed approach for designing this system is to implement a microcontroller-based control module that receives its instructions and commands from a cellular phone blue tooth. The arduino then will carry out the issued commands and then communicate the status of a given appliance or device back to the cellular phone.

1.7                                          LIMITATIONS OF THE PROJECT

The following is a list of limitations for the project.

·        The device can only work when the user is within the Bluetooth coverage.

·        Only devices with electrical controlling input ports will be possible targets for control.

·        The receiver must have a power source (220vac) attached at all times.

·        Operation of the controlling unit is only possible through a cell phone with Bluetooth capabilities.

·        Bluetooth has a range of 10-15 meters, so this device can switch ON and OFF any electronic appliance within the range.

1.8                        PROBLEMS AND ASSUMPTIONS OF THE PROJECT

The following is a list of problems and assumptions for the project;

·        The user and control unit will establish communication via bluetooth.

·        The controlled appliances will have to have an electrical interface in order to be controlled by arduino.

1.9                                                         PROJECT ORGANISATION

The work is organized as follows: chapter one discuses the introductory part of the work, chapter two presents the literature review of the study, chapter three describes the methods applied, chapter four discusses the results of the work, chapter five summarizes the research outcomes and the recommendations.
