ABSTRACT
These days, the precariolls climate can be troublesome to individuals to dry their clothes
outdoors due to the unpredictable weather conditions such as rainy day. Sometimes, people also
often forget to bring in their clothes during rainy days. For working people, this would be matter
to look upon as they lack time to manage their daily chores and routine. From this case, an idea
was developed to prevent the clothes which are dried outdoors to be exposed to rain and cause
the clothes to be wet. This product can run automatically using a microcontroller for the main
control system. The main objective is to design a compartment and design an electronic system
to automatically retrieving-out the clothes on sunny days and retrieving in the clothes on rainy
days. To make this system function properly, needed a linear actuator as the mechanical
mechanism, light dependent resistor (LOR), rain sensor module, and temperature sensor LM35.
All programs from the sensor wa installed using Arduino UNO which will provide an instruction
for the system to run properly. Advantages of this product are that is energy and time efficient,
and is easier for employed people indirectly perform chores at home.

ABSTRAK
Hari-hari ini, iklim yang tidak menentu boleh menyusahkan kepada individu untuk
mengeringkan pakaian mereka di luar rumah kerana keadaan cuaca yang tidak menentu seperti
hari hujan. Kadang-kadang, orang ramai juga sering lupa untuk membawa masuk pakaian
mereka semasa hari hujan. Bagi orang yang bekerja, ini akan menjadi perkara untuk melihat
kepada mereka kekurangan masa untuk menguruskan kerja-kerja harian mereka dan rutin. Kes
ini, idea yang telah dibangunkan untuk mengelakkan pakaian yang dijemur di luar rumah akan
terdedah kepada hujan dan menyebabkan pakaian untuk menjadi basah. Produk ini boJeh
berjalan secara automatik menggunakan mikropengawal untuk sistem kawalan utama. Objektif
utama adalah untuk mereka bentuk petak dan mereka bentuk sistem elektronik untuk
mendapatkan semula keluar secara automatik pakaian pada hari yang cerah dan mendapatkan
scmula dalam pakaian pada hari hujan. Untuk membuat fungsi sistem ini dengan betul,
memerlukan penggerak linear sebagai mekanisme mekanikal, cahaya perintang bersandar
(LOR), modul sensor hujan, dan sensor suhu LM35. Semua program dari sensor telah dipasang
menggunakan Arduino UNO yang akan memberikan arahan untuk sistem untuk berjalan dengan
betu!. Kelebihan produk ini adalah bahawa adalah tenaga dan masa yang cekap, dan lebih mudah
bagi orang-orang yang bekerja secara tidak langsung melakukan kerja-kerja di rumah.

CHAPTER 1
INTRODUCTION
1.1 Background Information
Most of people nowadays especially women will face difficulty to pick lip
their hanging clothes when it comes to unforeseen circumstances such as rainy day. For
instance, when women were busy with their other important works or not available at
that time, suddenly rain falls and the clothes will be wet because of exposure to rain.
For working people, they need to worry of their hanged clothes that have been dried
outside. Todays, people do not have ample time to manage their clothes as of many
important things to be done daily. Thus, it may affect their time to do some chores,
especially for houses that do not have maids or helper.
This project focuses on the laundry and drying issue. The weather can
change instantly from hot sunny days to rainy days, as for those working away from
their house which do not have any helper or a working couple where it is hard to
manage their laundry where the cloth is dried through the whole day without any proper
protection. In order to reduce their problem, the project proposed an automatic
clothesline. This clothesline will able to detect the surrounding several rain , temperature
and light factors. If they show any of these factors, the clothesline will move into the
chamber. Or else, it will remain outside under the given factors until the clothes dry
naturally_

1.2 Women with Profession
Datuk Dr Noorul Ainur Mohd Nur, secretary-genera l from Women, Family
and Community Development Ministry ' s was said in Star Online 20 II , the female labor
force participation rate in Malaysia was 47.9 percent, which was below the average of
other East Asia and Pacific countries based on the World Bank report. By the year
2015, Malaysia is expected to have 55 percent of women in its labor force [I]. Many
studies have shown the significance growth of global and local economy has
contributed by women owned business. Over the past decade the growth has been
increase [2]. Year by year the association of women in Small Medium Enterprise
(SME) industry was built because of their mindfulness and inspiration to overhaul their
economy and jobless among graduate students from university force themselves to
involve all hands on deck. Subsequently, the mental ity of women specialists which are
exceptionally dedicated skill and proactive that ambitious people reality will assume
control by women [2].
Women in Malaysia have been for a long time in the labor force. In any
case, the cooperation of women in Malaysia holding higher managerial positions is
uncommon in spite of the fact that women have higher instruction capability and
experienced compared to men [3]. It is unexpected in comparison to the current
situation whereby after more than 20 years since women entered the labor force, women
are hardly found in higher managerial positions. Numerous organizations still
underestimate that men make a more efficient managerial pioneers compared with
women. While in many Malaysian organization, a delicate issue about whether is the
circumstances of elevating proficient women to top administrations positions [3].

1.3 Malaysia in Equator Line
Malaysia experience ram, state and damp throughout the year because
Malaysia is located on top of the equator line. Throughout the whole year equatorial
regions are characterized by wet months and there is no alteration of summer and winter
as in temperature regions. However, the climate in South East Asia, where Malaysia is
located, is strongly seasonal because of the different monsoons caused by the changed
in the direction and speed of airstreams.
Malaysia is never excessively hot because Malaysia basically observes by
tropical climate. Except for high highlands, the atmosphere is considered decently hot
and greatly sultry. Throughout the year, the average temperature for every month IS
between 20°C to 30°C.
Round the year, Malaysia generally accomplish tropical climate. However,
the rainstorm differs on the coastline of Peninsular Malaysia. The rainy season reaches
out from September to December on the west coast, whereas on the east coast receive
rainfall from October to February. As regards East Malaysia, between the months of
November to February it gathers overwhelming rains.
Normal precipitation of mean annual cumulative ram m Malaysia is
2400mm to 3200mm [4]. From November to February is the crest month in Malaysia to .., become monsoon season, however on the west coast, August turns out to be the wettest
month. In general days are warm and nights are really cool in Malaysia. Furthermore,
its average climate is continually welcoming.
Therefore, all house need to have the automated clothesline to save their
clothes from getting wet on rainy day.

1.4 Migrant Maids
As more married women choose to participate in the workforce, the demand
for migrant maids by households in Malaysia has increased rapidly [5]. According to
statistic there are 729,809 workers from Indonesia and 189,500 of them work as a maid.
The maid has become an integral member of many families in Malaysia. Detail
indicates that in 2012 there are currently about 230,000 foreign maids in Malaysia and
the number could achieve 300,000 if Indonesian maids return to the nation [6].
Simple comparisons of families without housemaids and those with maids,
suggesting that utilize maids can raise female labor force participation rates of their
employers by 26 percentage points. By estimate the treatment effect of having a foreign
maid the rise in female labor force participation is estimated by Propensity Score
Matching (PSM) methods to be only 18 percentage points in 1993/1994. Moreover, this
effect appears to have decrease to only 13 percentage points from 2004/2005 . The
minor impact of taking maids is more leisure time for Malaysian women and financial
losses to the host households [5].

1.5 Problem Statement
During rainy day, most of people facing problems to pick up their hanging
clothes especially when it comes to unexpected circumstances, sllch as when working
people are caught up with doing other commitments works or not available during that
time.
Moreover, Malaysia is located on top of the equator line, it causes to
experience rain state and damp during the year. This matter sometime causes problem
with the labor force when washed clothes are not dry and have an unpleasant smell.
Besides, it will be more difficult to the family if they do not have helpers or
maid that will assist in doing the house chores. However, for middle class family, they
cannot afford to hire a maid. Since, the salary of the maid is increasing year by year.
1.6 Objectives
The objectives of this research are:
i. To develop and create an automated cloth hanger that suitable with the climate
ii. To design the electronic circuit system using Fritzing and Arduino software
iii. To forecast the problem happens if the automated cloth hanger is operated In..., real environment.

1.7 Scope of Project
This project will focu s on clothesline to lighten the burden to anyone who has a
laundry issue. Mostly, there are some scopes in this project which are to design the
electronic circuit of the system and design the compartment. This project will function in
two condition where first when raining, rain sensor detect water and second when it gets
dark LDR detect a light. The movement of the clothesline back and forth from the
compartment is by using linear actuator.
1.8 Thesis Outline

CHAPTER 2
LITERATURE REVIEW
2.1 Introduction
Nowadays, people always having problem picking up their cloths if it is
raining. Where, Malaysia is one of the countries with an unpredictable weather. The
weather might be rain in the morning and sunny in the afternoon or vice versa. As this
project, is to make certain that their cloth doesn't get wet by rain anymore. It is also to
reduce the energy used such as avoiding the used of dryer machine. By proposing this
project which is the automated drying rack, it will make human job easier by creating
this rack which depend on the light intensity and water or moisture. Using this drying
rack, people can leave their clothes on the rack without worried of wet cloth but it will
remain dry.
.... 2.2 Factors that affects the formation of rain correlation
The main consideration which is measured was the atmospheric pressure and
other parameters included atmospheric temperature and humidity [7]. As for this
project, we will stress more on the temperature factor. The temperature was
investigated to get the average specific temperature before rainfall.
7
2.2.1 Temperature that affects the formation of rain correlation
The condition for rainfall and cloud formation was affected by the higher
temperature. Heavy rainfalls such as the summer thunderstorms are influenced more by
the temperature than rain from larger widespread rain systems. Heavy rain has far
reaching consequences for people nowadays, and these could worsen at high
temperatures. Volume of rain that sprays in a heavy shower depends on the amount of
water vapor in the atmosphere. At higher temperatures, the amount of water vapor is
higher, thus increase the chance of heavy rainfall. The properties of a rain shower are
strongly depend on the time frame being studied, which from five minutes to several
hours even days. The various types of precipitation are created in different process in
the atmosphere.
Rain-rate distribution and rain drop size are important parameters used for
reducing the prediction rate. There are three ranges of rainfall thresholds which are 0.1
lOmmIhr are light precipitation, lO.l-30mmlhr moderate rainfall and more than
30mmlhr consider as heavy rainfall that was analyzed the rainfall over which Kuching,
Sarawak.
2.3 Technology on Smart Cloth line
In today 's available,time of the innovation was developed more family unit
tasks was changed over to a modem ways. It was quite a while back that the general
population utilizes a ton of endeavors and devotion for their works even there is a way
