Portable electronic devices are integral components in our daily life. Every

day new products are introduced to the market that utilizes embedded

computers in novel ways. In recent years, hardware such as

microprocessors, microcontrollers, and FPGA chips have become much

cheaper. Embedded systems are often required to provide Real-Time

response. The main elements that make embedded systems unique are its

reliability and ease in debugging. Some of the main devices used in

embedded products are Microprocessors and Microcontrollers.

Microprocessors are commonly referred to as general purpose processors

as they simply accept the inputs, process it and give the output. In contrast,

a microcontroller not only accepts the data as inputs but also manipulates

it, interfaces the data with various devices, controls the data and thus finally

gives the result. The project Rain detection with automatic closing of

window using AT89S52 Microcontroller is an exclusive project that can

control the servo motor according to the instructions given by the above

said microcontroller based on rain moisture sensor.

1.Introduction

An embedded system is a computer system designed to perform

one or a few dedicated functions often with real-time computing

constraints. It is embedded as part of a complete device often

including hardware and mechanical parts. By contrast, a

general-purpose computer, such as a personal computer (PC), is

designed to be flexible and to meet a wide range of end-user

needs. Embedded systems control many devices in common use

today.

Embedded systems are controlled by one or more main

processing cores that are typically either microcontrollers or

digital signal processors (DSP). The key characteristic, however,

is being dedicated to handle a particular task, which may require

very powerful processors. For example, air traffic control

systems may usefully be viewed as embedded, even though they

involve mainframe computers and dedicated regional and

national networks between airports and radar sites.

Since the embedded system is dedicated to

specific tasks, design engineers can optimize it to reduce the size

and cost of the product and increase the reliability and

performance. Some embedded systems are mass-produced,

benefiting from economies of scale.

Physically embedded systems range from

portable devices such as digital watches and MP3 players, to

large stationary installations like traffic lights, factory

controllers, or the systems controlling nuclear power plants.

Complexity varies from low, with a single microcontroller chip,

to very high with multiple units, peripherals and networks

mounted inside a large chassis or enclosure.

Real-time embedded system: Embedded systems which are

used to perform a specific task or operation in a specific time

period those systems are called as real-time embedded

systems. There are two types of real-time embedded systems.

• Hard Real-time embedded systems

• Soft Real Time embedded systems

2. Reset button

3. Crystal oscillator

4. Regulated power supply (RPS)

5. LED indicator

6. Stepper motor

7. Rain sensor

Microcontrollers and Microprocessors are widely used

in embedded systems products. Microcontroller is a

programmable device. A microcontroller has a cpu in

addition to a fixed amount of RAM , ROM, I/O ports and

a timer embedded all on a single chip. The fixed amount

of an-chip ROM , RAM and number of I/o ports in

microcontroller makes them ideal for many

applications in which cost and space are critical.

Microcontroller are used in devices such as automobile

engine control systems, implantable medical devices,

remote controls, office machines and many others. By

reducing the size and cost compared to a design that

uses a separate microprocessor, and memory,

microcontroller makes it economical to control more

devices.

3: SOFTWAREDESCRIPTION

This project is implemented using following software’s:

• KEIL compiler

• PROTEUS

• CIRCUIT DIAGRAM

KEIL

Keil compiler is software used where the machine

language code is written and compiled. After compilation, the

machine source code is converted into hex code which is to be

dumped into the microcontroller for further processing. Keil

compiler also supports C language code.

PROTEUS

Proteus is software for microcontroller

simulation, schematic capture, and printed circuit

board design. it is developed by “Lab center

Electronics”.Proteus is a Virtual System Modeling that

combines circuit simulation, animated components

and microprocessor models to co-simulate the

complete microcontroller based designs. This is the

perfect tool for engineers to test their microcontroller

designs before constructing a physical prototype in

real time.

5 RESULTS

5.1 Result:

The project “Rain detection with automatic

closing of window ” was designed to control the window

automatically based on the rain sensor detection. Rain operated

motor was designed based on conduction sensor (Tough sensor)

circuit, Control Unit, stepper motor . The sensor was used to

detect the rain or water flow. Therefore when it senses window

closes automatically & opens when it is not in contact with rain

or water flow.

5.2 Conclusion:

Integrating features of all the hardware components used have

been developed in it. Presence of every module has been

reasoned out and placed carefully, thus contributing to the best

working of the unit. Secondly, using highly advanced IC’s with

the help of growing technology, the project has been successfully

implemented. Thus the project has been successfully designed

and tested

5.3 Future Scope:

Our project “Rain detection with automatic

closing of window” is mainly intended to design an automatic

wiper which operates automatically as soon as rain sensor gives

the input.

The aim is to design and develop a control system

based an electronically controlled automotive rain operated

motor is called RAIN DETECTION WITH AUTOMATIC CLOSING

OF WINDOW. Rain operated motor is consists of conduction

sensor (Tough sensor) circuit, Control Unit, wiper motor and

glass frame. The sensor is used to detect the rain or water flow.

There is any rain on the class, the sensor senses the rain or flow

water and giving the control signal to the wiper motor.

The battery supplies the power to the sensor as

well as rain operated motor. Wiper motor is automatically ON

during the time of rainfall. The senor is fixed in the vehicle glass.

The conductive (Touch) sensor is used in this project. It senses

the rainfall and giving control signal to the control unit. The

control unit activates the wiper motor automatically. This

operation is called Rain detection with automatic closing of

window. This project can be extended using high efficiency GSM

module. The GSM module gives the intimation of the person with

this system through SMS
