2. 1.INTRODUCTION
We designed a sensor system that detects rain and rolls up the windows
The object is to grant the driver the convenience of having his or her car windows automatically close in
the event of rain
3. Features
● Rolls up windows in unattended
vehicle when it begins to rain
● Only activated when car ignition is off
● Window stops if obstruction in pathof
window.
● Easily interfaced with power windows
in vehicles
4. Benefits
• Protects the inside of a vehicle from water damage caused by rain
• Provides convenience to drivers by allowing them to keep windows open while
they are away and not having to rush out to close them if it begins to rain
5. The main blocks are:
1. Micro controller (AT89S52 )
2. Reset button
3. Crystal oscillator
4. Regulated power supply (RPS)
5. LED indicator
6. Stepper motor
7. Rain sensor
7. SOFTWARE DESCRIPTION
This project is implemented using following
software’s:
• KEIL compiler
• PROTEUS
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.
8. Proteus is a software used for microcontroller simulation, schematic capture, and printed circuit
board design.
It is developed by “Lab centre Electronics”.
Proteus is a Virtual System Modelling 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.
PROTEUS
10. ● Compatible with any car with power
windows
● Automatic drying with complete
rooftop coverage
● Compact and easy to install
● User-override switch
Product Features
Reliable and low cost
11. Advantages
● ➨Operating principle is very easy.
● ➨It consumes less power for operation.
● ➨Installation of rain sensor based systems are very much
simple.
● ➨Individual rain sensor costs very less.
12. Disadvantages
● ➨The rain sensor based system functions when water falls on the sensor
directly.
● ➨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.
13. 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
