ABSTRACT

Smart Home System technology began more than a decade to introduce the concept of

network devices and equipment in the home. According to the Association of Smart Homes, the

best definition of smart home technology is: the integration of technology and services through

home networks for a better quality of living. Its is because most of user use the old ways that use

the system manually such as often open mailbox for checking letter. To overcome this problem a

smart control based system has been proposed. Many of the tools used in computer systems can

also be integrated into Smart Home Systems. In this project, I reduce the scope of the Smart

Home System that just focus on how to secure the postage with notification. This device will

help and ease the user in their daily life .

ABSTRAK

Teknologi Home Smart System bermula lebih daripada satu dekad untuk memperkenalkan

konsep peranti dan peralatan rangkaian di rumah. Menurut Persatuan Rumah Pintar, definisi

teknologi pintar rumah pintar adalah integrasi teknologi dan perkhidmatan melalui rangkaian

rumah untuk kualiti hidup yang lebih baik. Ia adalah kerana kebanyakan pengguna menggunakan

cara lama yang menggunakan sistem secara manual seperti peti mel yang sering dibuka untuk

memeriksa surat. Untuk mengatasi masalah ini, sistem berasaskan kawalan pintar telah

dicadangkan. Banyak alat yang digunakan dalam sistem komputer juga boleh diintegrasikan ke

Smart Home Systems. Dalam projek ini, saya mengurangkan skop Sistem Rumah Pintar yang

hanya memberi tumpuan kepada cara untuk mengamankan pos dengan notifikasi. Peranti ini akan

membantu dan memudahkan pengguna dalam kehidupan seharian mereka.

CHAPTER 1

INTRODUCTION

1.1 Background

Smart Home System: Secure Postage with Notification is design to overcome the

problem that face by people nowadays who cannot control/monitor their postage in daily

life. This project work similar to letterbox or pigeon hole where the letter or postage will

be placed in their letterbox or pigeon hole. The method of checking letter or postage in

mailbox has not updated until today where most people still checking the mailbox by them

self every day.

For this project, the electronic technology or the internet of things (IOT) was

applied to overcome this problem. This project is build up by using Arduino Uno and secure

with Radio-frequency identification (RFID). The installed sensor in the project will start

function once it detect the document/letter/postage receive and automatically send alert

signal via notification on smartphone. This project also make people life easier by sending

short message notification to notify the user about the postage or letter receive and save

time in checking the mailbox every day.

This project can operate automatically without the human inspection. When the

project completed, people do not have to repeatedly go to their mailbox to check whether

a mail or postage is deliver or not. People also will never worry of forgetting to pick up

their mail or postage as there will be instant notification about the delivered mails or

postage.

1.2 Problem Statement

There are several problems that have been identify in this project. This

problem statement will be the core statements in replacing the existing mailbox

system which are:

i) People busy with daily life.

People is too busy working from morning and come back home at night.

Sometimes they forgot to check whether the mailbox has postage or letter in it.

People also tired to check the mailbox regularly and the mailbox are often located

outside the house as they must walk to check the mailbox.

ii) Waste time.

If the mailbox is outside the house, it might take a time to collect their

postage or letter. If they are waiting for important postage, they might check the

mailbox regularly. It is frustrated if they come from the high floor and looking from

their postage, but the postage is not there yet or the mailbox is empty.

` iii) Anyone can steal the postage

The user sometimes are too busy and sometimes the user not at home in

long time period. The possibility of others people to steal are high and maybe the

mail or postage are very important to the user.

1.3 Objective

1. To design the Smart Home System, secure postage notification.

2. To implement the design of the model into Smart House System.

3. To test evaluate whether the Smart House System is fully functioned.

1.4 Scope

This Project focuses on two scope:

1. Scope of client which is to all people that have house.

2. Scope of technology which is tis technology will use Arduino kit.

1.5 Limitation of work

This project is only work in a wireless network connection to send the notification

Because of the notification will be deliver to user when the project connect to home

wireless network. Next, this project only use the battery for power supply.

1.6 Expected Result

At the end of this project, the expected outcome from this project will be the Smart

Home System, Secure Postage with Notification is fully developed, installed and

functioned for user to use. (Refer Chapter 5.2)

System

The article [4] is Smart Pigeonhole using Short Messenger System.

This system is a hardware that operates by using Arduino Yun, infrared sensor

and adjustable sensor that will inform the user about mail that got into the

pigeonhole. Every mail that got into the pigeonhole will alert a phone by

sending message to the user. The system designed by using IR sensor that acts as a

detector to detect the letter that arrive. The IR sensor is placed on the top of the

mailbox. It locate in the good position to make sure it can detect the mail arrive

accurately in every time the mailman inserts the mail. This sensor is an

adjustable sensor. User can adjust the transmitter and receiver. It will be

mounted to the board and will be connected with the arduino yun board.

Figure 6: Flowchart of the Smart Home System Figure 7: Flowchart of the RFID Reader

The flowchart of the Smart Home System shows that when the power is on, all of the

component will start working, the ESP8266 will connect to the wireless network. When the

network establish, the Ultrasonic sensor will generate pulse. When the waves of the pulse hits an

obstacle, it will reflect back to the receiver to get reflection time. The Ultrasonic sensor will

generate pulse of wave in every 1 minute. Then if the Ultrasonic sense the obstacle, the information

will be send to the user’s smartphone.

The second flowchart that the flowchart of the RFID Reader shows that when the

power is on, the RFID Reader will start working. When the user swipe the RFID, the RFID

Reader will scan and reader the detail and try to match the detail. If the detail is not match,

message will be send to user’s smartphone, tell that someone try to open the mailbox. If

the detail is match, the mailbox door will be open and the detail will be send to user’s

smartphone.

3.2.4 Implementation

After the design phase has been develop, the configuration and the coding of the

Arduino is implement. The circuit is installed and connected. The coding for the pulse of

waves include the 1-minute looping time for generate the pulse. If else rule is used in the

coding to determine whether there has obstacle or not.

3.2.5 Testing

In this step the complete circuit will be test. If there is still error occurred, it will be

solve in this step. If there is any change need to implement, the project must start back at

design step for revision flow.
