Blind Walking Stick With Sensor Project

Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. The blind stick is integrated with ultrasonic sensor along with light and water sensing. One is the main circuit which will be mounted on the blind man s stick.

Blind walking stick with sensor project.

The generally available blind walking sticks are capable of finding obstacle that touch the stick physically. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. It is helpful to a blind person but we here propose an advanced blond stick system that. The other is a small remote rf transmitter circuit which will be used to locate the main circuit.

On sensing obstacles the sensor passes this data to the microcontroller. In this project we will learn how to design blind walking stick using arduino ultrasonic sensor hc sr04. Smart blind stick project using arduino and sensors. The arduino uno then processes this data and calculates if the obstacle is close enough.

Almost 30 million people are blind according to the recent who report. You can buy all the required components used in this project from here. This arduino smart blind stick project requires two separate circuits. This is the reason why we have designed the blind walking stick device which will help blind people to walk with ease independently.

The blind stick is integrated with ultrasonic sensor along with light and water sensing. These blind people are totally dependent on others as they can t walk alone. On sensing obstacles the sensor passes this data to the arduino uno.
