3. INTRODUCTION
✔ The main aim of the project is to design a voice based alerting system
for the blind people.
✔ UV sensor senses the obstacles in its path by continuously
transmitting the UV waves.
✔ The controlling device of the whole system is a micro controller.
✔ The system is very helpful for blind people.

4. OBJECTIVES
✔Voice based alerts
✔Obstacle detection
✔Low cost solution
✔Low power consumption

5. EXISTING MODEL
✔In the previous model, we have used PIC18F452 micro controller.
✔It is 8-bit micro controller and does not support to access more equipment.
✔In this model only IR sensors were used.
✔This model do not supports the motion sensing sensors.
✔High power consumption.

6. PROPOSED MODEL
✔We are using cortex M3 micro controller in our project.
✔It is an 32-bit micro controller.
✔The length will be comparatively small and more memory.
✔We can able to access more equipment.
✔It supports all type of sensors.

7. EQUIPMENTS USED
✔Microcontroller(M3)
✔Regulator power supply
✔IR senor
✔Voice circuit
✔Buzzer

9. APPLICATION
✔Security Systems
✔Interactive Animated exhibits
✔Parking assistant system
✔Robotics Navigation

10. ADVANTAGES
✔Guides blind people
✔Alerts through voice based message system
✔Obstacle detection using UV distance finder sensor
✔Efficient low cost design

11. CONCLUSION
✔This device will help the blind person be more alert above the obstacles
✔This project is mainly for blind people to avoid obstacles by themselves
✔This project provides efficient and economical security system
