3. OBJECTIVE
• To Develop a windshield wiper
mechanism which is more
effective in terms of power input
and size it occupies.
• Come up with a mechanism of a
windshield wiper which is
friendly to the environment and
actually provide safety to the
operators.
4. ABSTRACT
• Aggressive research towards
safety & reliability.
• Relatively uncommon in modern
vehicles.
• They are often too expensive, too
unsightly, or too unreliable.
• Many attempts are being made to
overcome following
circumstances.
5. INTRODUCTION
• The prototype has been
developed which is intended
towards revolutionizing the
automotive industry.
• The prototype of rain sensor
works on the principle of using
water for completing its
circuit.
6. EXISTING SYSTEM
• A rain sensor or rain switch is a switching device
activated by rainfall.
• In this the sensor projects infrared light into the
windshield at a 45-degree angle.
• If the glass is dry, then most of this light is reflected
back into the sensor by the front of the windshield.
• If water droplets are on the glass, then it reflects the
light in different direction.. the wetter the glass, the
less light makes it back into the sensor.
7. PROPOSED SYSTEM
• This proposed system is an automatic wiper system
that automatically switches ON on detecting rain and
stops when rain stops.
• Our project brings forward this system to automate
the wiper system having no need for manual
intervention.
• Our system uses rain sensor to detect rain, this signal
is then processed by microcontroller to take the
desired action.
10. COMPONENTS
8052 MICROCONTROLLER:
• The 8052 is another member of the 8051 family.
• The 8052 has all the standard features of the 8051 as well as
an extra 128 bytes of RAM and an extra timer.
• 8052 has 256 bytes of ram and 3 timers.
• It has 8K bytes of on-chip program ROM instead of 4K
bytes.
11. COMPONENTS
RAIN SENSOR:
• The rain sensor module is an easy tool for rain detection.
• Raindrop sensor is basically a board on which nickel is coated in
the form of lines.
• It can be used as a switch when raindrop falls through the raining
board
• The analog output is used in detection of drops in the amount of
rainfall.
12. COMPONENTS
LM 358 COMPARATOR:
• A Comparator is a device that compares two voltages or
currents and outputs a digital signal indicating which is larger.
• It has two analog input terminals V+ & V- and one binary digital
output Vo.
• Pin description of LM358 is given below.
13. COMPONENTS
LCD MODULE:
• LCD screen is an electronic display module and find a wide range
of applications.
• These modules are preferred over seven segments and other multi
segment LED’s.
• The reasons being: lcds are economical; easily programmable; have
no limitation of displaying special & even custom characters
(unlike in seven segments), animations and so on.
• The data is the ASCII value of the character to be displayed on the
LCD.
14. COMPONENTS
L293D DRIVER:
• L293D is a Motor driver integrated circuit which is used to drive DC
motors rotating in either direction.
• It is a 16-pin IC which can control a set of two DC motors
simultaneously.
• The L293D uses 5V for its own power and external power source is
needed to drive the motors, which can be up to 36V and draw up to
600mA.
15. COMPONENTS
DC SERIES MOTOR:
• A DC motor in simple words is a device that converts direct
current(electrical energy) into mechanical energy.
• We in our project are using brushed DC Motor, which will operate
in the ratings of 12v DC 0.6A
• The complete operation of DC motor is controlled by an electronic
device called L239 Driver.
16. SOFTWARES USED
• KEIL µvision
• Keil µvision is a compiling software for embedded C.
• the machine source code is converted into hex code which is to be dumped into the microcontroller for
further processing.
• PROTEUS
• Proteus software tool was developed by Labcenter Electronics Ltd.
• The Proteus Design Suite is a proprietary software tool suite used primarily for electronic
design automation.
19. ADVANTAGES
• It extends life of rain sensor based systems such as car wiper, irrigation systems by running them
only when it is necessary.
• Operating principle is very easy.
• It consumes less power for operation.
• Installation of rain sensor based systems are very much simple.
DISADVANTAGES
• The cost of overall system increases as additional components are needed along with rain
sensor.
• In order to avoid false detection of rain, it requires rain sensors to take decision after few
minutes.
21. RESULTS AND CONCLUSION
• The following prototype shows us the working of automatic rain sensing car wipers.
• The results can be observed in LCD display as following,
➢ “Normal State” – When there’s no rain sensed by the sensor.
➢ “Its Raining” – When sensor senses a rain.
