ABSTRACT
Due to the rate of damages that occur to our industrials and homes possessions
during rainfall. This rain alarm will give you an alarm indication the instant it starts
to rain, hopefully giving you time to close windows and bring in possessions in our
homes and to keep so many of our industrial machines in a proper place. The alarm
has also the ability to indicate when it stops raining, by that time the alarm will stop.
This project was designed to indicate when it is raining and also to indicate when the
rain has stop. Apart from these two applications, there are other applications that
this alarm has which would be mentioned in this work.

CHAPTER ONE
INTRODUCTION
1.1 BACKGROUND OF THE STUDY
RAIN SENSOR is one of the kind of switching device which is used to detect the rainfall. It works
like a switch and the working principle of this sensor is, whenever there is rain, the switch will
be normally closed.
In 1958, the Cadillac Motor Car Division of general motors experimented with a water-sensitive
switch that triggered various electric motors to close the convertible top and raise the open
windows of a specially-built Eldorado Biarritz model, in case of rain.
Raindrop sensor is basically a board on which nickel is coated in the form of lines. It works on
the principal of resistance.
Rain sensor module allows to measure moisture via analog output pins and it provides a digital
output when a threshold of moisture exceeds. The module is based on the IM393 op amp. It
includes the electronics module and a printed circuit board that collects the rain drops. As rain
drops are collected on the circuit board, they create paths of parallel resistance that are
measured via the op amp.
The sensor is a resistive dipole that show less resistance when wet and more resistance when
dry. When there is no rain drop on board it increases the resistance so we get high voltage
according to V=IR. When rain drop
Water Management and proper water usage has to be maintained in the recent years. So
maintain proper usage of water we need to save the water in every aspect. In agriculture field
rain is a basic need but intense rain can affect the crops root growth. Irrigation is enough cover
the water need of crop but if intense rainfall occurs it may damage the crops, growth of the
crops. when Rain detector detects rain it trigger the alarm. Rain detector alarm efficient way to
stop irrigation whenever rain occurs. It is also used in home automation by users to reclaim
their belongings, cover windows. In some situations, we can Collect some rain water. When rain
falls, it will cause a setback to all the reasons for sun-drying enumerated above, especially when
the materials being sun dried are not retrieved quickly. Thus, designing and constructing a
device which gives one a heads-up the instant it starts to rain hopefully giving you time to
retrieve the materials being sun dried, close your
windows, and bring in possession is not only apropos but also absolutely imperative. Also, since
it can rain at any time without any warning, clothes in a clothes line outside the house that are
almost dry may get wet if we do not realize it is raining on time. Thus, this project will also help
house wives and other users to be quickly alerted to avoid rain from wetting shirts/ dresses
being sun dried at the clothesline line outside the house. Collect some rain water.
Mankind has always harnessed the elements of nature for different purposes.
Water for irrigation and Electricity
generation (Fthenakis and Kim, 2010), wind for wind mill used for many applications ranging
from turning turbines that generate electricity, to quarry for crushing stones, sun for drying,
heating and generation of electricity (Mekhilef, Saidur and Safari, 2015). From time immemorial
humans used the sun to dry many things, a process known as sun drying. Sun drying is carried
out in the farm, home, industry, laboratory, hospitals and other institution for a number of
reasons (Amos,
2014). According to Anastasi et al. (2009) these reasons range from totally driving out water
molecules from the things being
dried like clothes, some farm produce.
When rain falls, it causes a setback to all the reason for sun-drying, especially when the
materials being sun dried are not
retrieved
quickly (Bagree, 2012). Thus, designing and
constructing a device which gives one a heads-up the instant it starts to rain, hopefully gives
one time to retrieve the materials being sun dried. Also, since it can rain at any time without
any warning, clothes in a clothing line outside the house that are almost dry may get wet again
if they are not retrieved on time.
Thus, this project will also help house wives and other users to be quickly alerted to avoid rain
from wetting shirts/ dresses being sundried at the clothes line outside the house (Barnaghi
et al., 2012).
Water/rain alarm detector is a self-contained electronic device that sounds an alarm when its
sensor is in contact with water.
It comprises of rain sensor (Jayant, 2015) and microcontroller
(Hernando, 2016). It can be used near water heaters, washing

LITERATURE REVIEW
2.1 HISTORICAL BACKGROUND
Rain detector and alert systems have played a crucial role in human history, providing early
warnings of impending rainfall and mitigating its potential hazards. From ancient rudimentary
methods to modern sophisticated technologies, the evolution of these systems reflects
humanity’s continuous quest for better understanding and adaptation to natural phenomena.
Ancient Methods:
Early civilizations devised simple methods to detect rain, primarily relying on observations of
the environment. Ancient peoples observed changes in the behavior of animals, such as birds
flying lower or seeking shelter, which signaled the approach of rain. Additionally, visual cues like
darkening clouds and drops in air pressure were noted as indicators of imminent rainfall. These
observational techniques formed the basis of early rain detection systems, enabling
communities to prepare for changing weather conditions.
Historical Milestones:
The development of rain detection technology underwent significant advancements throughout
history. In ancient China, the invention of the first mechanical rain gauge during the Han
Dynasty (206 BCE – 220 CE) marked a crucial milestone. This device, known as the “tipping-
bucket rain gauge,” measured rainfall by collecting water in a calibrated container, providing
quantitative data on precipitation levels.
During the Islamic Golden Age (8th to 14th century), scholars such as Ibn al-Haytham pioneered
advancements in optics and meteorology. Al-Haytham’s work on optics laid the foundation for
understanding atmospheric phenomena, including rain formation and cloud behavior. His
insights contributed to early meteorological theories and indirectly influenced the development
of rain detection methods.
In the 19th and 20th centuries, the Industrial Revolution spurred further innovations in rain
detection technology. Meteorological instruments, such as the barometer and hygrometer,
became standard equipment in weather monitoring stations worldwide. Concurrently, the
invention of telegraphy enabled real-time communication of weather observations, facilitating
the timely dissemination of rain alerts to distant locations.
Modern Technologies:
The advent of modern electronics and computing revolutionized rain detection and alert
systems. Doppler radar, introduced in the mid-20th century, revolutionized weather forecasting
by providing detailed insights into precipitation patterns and intensity. Doppler radar systems
detect rain by analyzing the reflection of radio waves off water droplets in the atmosphere,
enabling meteorologists to track storms with unprecedented accuracy.
In recent years, advancements in sensor technology and data analytics have led to the
development of innovative rain detection solutions. Remote sensing platforms, such as
satellites and unmanned aerial vehicles (UAVs), provide comprehensive coverage of global
precipitation patterns, enhancing the monitoring and prediction of rainfall events. Additionally,
the integration of machine learning algorithms enables automated analysis of weather data,
facilitating early detection of rain and timely issuance of alerts to at-risk communities.
Conclusion:
The evolution of rain detector and alert systems reflects humanity’s ingenuity and resilience in
adapting to changing environmental conditions. From ancient observational techniques to
modern sensor-based technologies, these systems have played a crucial role in mitigating the
impacts of rainfall-related hazards, such as floods and landslides. As technology continues to
advance, the future promises even more sophisticated and effective methods for detecting rain
and safeguarding vulnerable communities against its potential consequences.
