1.1 Background

Nowadays home is outfitted with many electrical home appliances that need to be controlled by people. However this may not be controlled by all the time because people may not be not at home all the time. We proposed a new technology so that the ordinary services of the mobile phones can be used to communicate with and control the home appliances. Here, the switch board of our regular use is replaced by Wi-Fi module which will communicate with microcontroller and the android based smart phone. The home appliances monitoring and controlling is done wirelessly through Android smart phone which user can monitor and can turns the ON/OFF the targeted electrical home appliances such as electrical fan and lamp remotely. The purpose of this project are for cost and energy saving.

(17)

The main objective of the project can be outlined as follows

 To design and fabricate a smart home system that is capable of monitoring and controlling the household appliances using Android application with the presence of Wi-Fi connection

 To evaluate and analyse the performance of the home controlling system and effective while using system.

1.3 Problem Statement

Nowadays, people are too busy in their daily routine and very often are away from home for working. Sometimes, they are forgotten to turn ON/OFF the appliances and as a result, the operation is put into operation for long hours. Thus, a project based on a microcontroller device using Android and Wi-Fi technology is developed. It can automatically control any electrical home appliances remotely using mobile phone. This project also can save cost and energy in daily life

1.4 Scope of Project

The main target of this project is to develop a system that can control and monitor the targeted home appliances by using Android and Wi-Fi technology.

CHAPTER 2 THEORETICAL BACKGROUND

2.0 Introduction

In this chapter, the literature review which contains the information and ideas in completing the project is discussed. There are several sources that had been taken as a resource such as books, thesis, journal and website. It was included the operation of the circuit, the hardware and software which is useful in the project. Other than that, in this chapter also make a study about several projects that related to make some improvement or take some idea from the other project. It is useful to complete a project that has created.

2.1 Smart Home and Controlling System

The development of digital information has led the rapid change in human lifestyle. The use of electricity is very important as one of the main source of energy that is vital in today modern life. Some kinds of mechanism using available technology could be used to reduce wastage in electricity usage. Thus a prototype based on a microcontroller device using Android and Wi-Fi technology is developed. It can automatically control any electrical equipment at home remotely using mobile phone. Hence the electrical energy saving in daily life can be made more efficient and effective.

As the technology grows, Wi-Fi and Android technology has been widely accepted as a part of medium of communication (Akyildiz, Su, Sankarasubramaniam, & Cayirci, 2002). The purpose of using this technology is to provide widest coverage at minimal cost. Therefore the use of Android and Wi-Fi would facilitate in controlling the electrical device at home from long distance and low in maintenance

(23)

proposed to develop a system is to facilitate the home owner to optimize usage of electricity remotely using smart phone with the presence of internet connection.

Lights and other electrical appliances turned on continuously and it leads to energy waste. Thus this research is carried out to provide a mechanism through the development of a prototype to provide a service to the home owner to optimize the usage of electricity through remote control using Android services. The followings are the objectives of the research project to ensure it meets the aim. (J, Lathkar, & B, 2014)

2.2 Research from Previous Project

Research from other previous projects was needed to complete this project. It was useful to upgrade the system that has been demonstrated before. Other than that, some other technologies that has been used in this project can get help from others study in this field to know the function and to master on technology that used in this project.

is based on various wireless technologies that can support some form of remote data

transfer, sensing and control such as Bluetooth, Wi-Fi, RFID, and cellular networks.

The next research is the home system project that use the technology of Radio

Frequency Identification (RFID) by (Darianian & Michael, 2008). The project introduces RFID reader system architecture for a home comprised of several readers in master slave architecture using network connectivity like WLAN RFID reader to read the identification information from the tags and exchange it with the back-end system for further processing.

(24)

Based on the mentioned literature review, there are a few flaws and disadvantages of these previous projects. For wireless Bluetooth implemented home automation system, there is limited range of connectivity since the effective area under control from a Bluetooth module is 100 meters in diameter (J et al., 2014). While for Ubiquitous home controlling system, which the system use the combination of a of Bluetooth and GSM technology, the disadvantages of these systems are twofold. Firstly, a high end personal computer has been utilized which not only increases the cost of installation but also increases the energy consumption. Secondly, development and hosting of web pages which also add to the cost. And the advantages of using GSM is users have to remember different AT commands to control the connected devices proposed mobile IP since that the users are not provided with a graphical user interface . The last disadvantage for project that use

RFID is it is also limited as they work only with reading distances up to 5cm. But

they are currently still too large, heavy and consume too much power compared to the mobile devices of today and are not very stylish for home environment and therefore not suitable for resilient long day usage. (Darianian & Michael, 2008). 2.3 Hardware and Software Review

This part is to review the hardware and software that will be used on this project. This part is very crucial as it explain some ctitical informations regarding parts and components for the hardware and some knowledge with the regards to the software.

2.3.1 Smart Phones as Controlling Device

A smartphone is a mobile phone with an advanced mobile operating system. They typically combine the features of a cell phone with those of other popular mobile devices, such as personal digital assistant (PDA), media player and GPS navigation unit. Most smartphones have a touchscreen user interface and can run third-party apps, and are camera phones. (Nusca, 2011). Smart phones gives the opportunity to the developers to create new applications for the advance smart phone usage (Hwang, 2012). According to a study made, smart phone
