Blind Walking Stick With Sensor Project

Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. 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.

This arduino smart blind stick project requires two separate circuits.

Blind walking stick with sensor project.

One is the main circuit which will be mounted on the blind man s stick. You can buy all the required components used in this project from here. The generally available blind walking sticks are capable of finding obstacle that touch the stick physically. In this project we will learn how to design blind walking stick using arduino ultrasonic sensor hc sr04.

The main board s circuit diagram is shown below. On sensing obstacles the sensor passes this data to the microcontroller. The other is a small remote rf transmitter circuit which will be used to locate the main circuit. It is helpful to a blind person but we here propose an advanced blond stick system that.

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. 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.

On sensing obstacles the sensor passes this data to the arduino uno. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. Smart blind stick project using arduino and sensors.
