On sensing obstacles the sensor passes this data to the microcontroller.
Blind walking stick with sensor.
We have created designed and built an ultrasonic blind walking stick device which will help blind people to walk with ease independently.
As a simpler version we have used only one ultrasonic sensor in this project.
This electronic walking stick is revolutionizing the way that blind people can navigate the world.
A young research scholar from the applied mechanics department of motilal nehru national institute of technology mnnit has designed a sensor based high tech walking stick for blind persons.
All the feedbacks will be given to the blind man through a buzzer.
The light stick was designed by wu guanghao and is the ultimate walking stick for the visually impaired.
Using this smart blind stick a visually impaired person can walk without anyone s help.
Currently in order for a blind person to navigate any given publicly accessible building they.
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.
This smart stick will have an ultrasonic sensor to sense distance from any obstacle ldr to sense lighting conditions and a rf remote using which the blind man could remotely locate his stick.
The smart blind stick automatically detects the obstacle in front of the person and give him a response to the person by vibrating the stick and also with a warning sound.
For better accuracy and assistance two or three sensors can be used.
This stick makes life much easier for those who are blind by power packing a regular walking stick with helpful technology.
Our system uses ultrasonic sensor to sense objects within a certain range of the person and sounds beeps of a particular type to signal obstacles.
Sajal babu the research scholar who has developed this stick under the guidance of professor ravi prakash tiwari has named it smart blind stick.
One of the main features of the light stick is its obstacle sensor that alerts users of objects ahead of them.
Blind walking stick using arduino ultrasonic sensor hc sr04 blind walking stick using arduino ultrasonic sensor hc sr04.
To design blind walking stick using.
Also we use a sorting system to detect water in.
Through this the blind person can aware about the obstacles in front of him.
