2. INTRODUCTION
 The system facilitates blind people to navigate independently without any
external help.
 The system is linked with a GSM-GPS module to pin-point the location of the
blind person and to establish a two way communication path in a wireless
fashion.
 The system is equipped with obstacle sensors such as ultrasonic and IR
sensor to alert the blind person .
 Temperature sensor is used to monitor the body temperature of blind
person and alert via gsm module.
 color sensor as audio labeler device for reading printed color-code.
 all color-code readers contain decoder circuitry analyzing the color-code
image data provided by the sensor and sending the color-code content to the
scanner's output port.

18V, 24V.
Voltage regulator ICs is available with fixed (typically 5, 12 and 15V) or
variable output voltages. The maximum current they can pass also rates them. Negative
voltage regulators are available, mainly for use in dual supplies.

8. BATTERY
Battery (electricity), an array of electrochemical cells for electricity storage,
either individually linked or individually linked and housed in a single unit.
An electrical battery is a combination of one or more electrochemical cells, used to
convert stored chemical energy into electrical energy.
Lead-acid batteries are the most common in PV systems because their initial
cost is lower and because they are readily available nearly everywhere in the
world.
Features:
•Manufactured/tested using CAD
•Electrolyte volume
•PE Separators Protection against leakage

9. • Detects obstacle around 50cm range.
• operates between 25 kHz and 500 kHz.
• 5v operating voltage.
ULTRASONIC SENSOR

10.  Impedance Moisture sensors are used.
 For the water sensor we use two metallic plate under the
stick ,when water touches on this stick then buzzer is on.
WATER SENSOR

11. TCS3200 is a colour sensor which can detect any number of colour with right
programming. TCS3200 contains RGB (Red Green Blue) arrays. As shown in figure
on microscopic level one can see the square boxes inside the eye on sensor. These
square boxes are arrays of RGB matrix. Each of these boxes contain Three sensors,
One is for sensing RED light intensity, One is for sensing GREEN light intensity and
the last in for sensing BLUE light intensity.

14. SOFTWARE IMPLIMENTATION
Keil MicroVision is an integrated development environment used to create software to
be run on embedded systems.
μVision3 is an IDE (Integrated Development Environment) that helps write,
compile, and debug embedded programs. It encapsulates the following
components.
•A project manager.
•A make facility.
•Tool configuration.
•Editor.
•A powerful debugger.

15. To create a new project in uVision3:
1.Select Project - New Project.
2.Select a directory and enter the name of the project file.
3.Select Project –Select Device and select a device from Device Database.
4.Create source files to add to the project
5.Select Project - Targets, Groups, and Files. Add/Files, select Source Group1, and
add the
source files to the project.
1.Select Project - Options and set the tool options. Note that when the target device is

22. CONCLUSION
This paper presents a theoretical model and a system concept to provide a smart
electronic aid for blind people. This system is intended to provide overall measures –
object detection and realtime assistance via Global Positioning System(GPS).The
system consist of ultrasonic sensor, GPS Module, GSM Module and vibratory

Travelling Aid (ETA) kit to help the blind people to find obstacle free path. This ETA
is fixed to the stick of the blind people.
Increasing the range of the ultrasonic sensor and implementing a technology for
determining the speed of approaching obstacles.
Synchronization with external memory to increase the number of routes stored.
Synchronization with various navigation software applications available on the
internet so that new, un-programmed destinations can also be chosen.
 Provision for voice control using speech recognition.
