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.
Smart blind stick with ultrasonic sensor abstract.
Presented here is a smart stick using arduino uno.
This arduino board is small enough to install on a regular stick and has buzzer ldr sensor ultrasonic sensor and a water detector sensor interfaced to it.
Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity.
It is well known that the blind people carry a hand stick with them whenever they need a support.
The main aim of this project is to assist the blind persons without the human need.
Ultrasonic sensor sends high frequency pulses these pulses reflects from object and takes as echo time between echo and trig is measured by the microcontroller or arduino which is.
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 all the feedbacks will be given to the blind man through a buzzer.
Blind stick is an innovative stick designed for visually disabled people for improved navigation.
Abstract the purpose of this paper is to design construct and do a performance test of a smart walking stick with object detection and recognition.
It cost me just 10 to make one.
Person suffering from night blindness cataracts glaucoma albinism or injury.
Obstacle detection is one of the major concerns for a fully or a partially blind person e g.
Ultrasonic blind walking stick as shown in diagrams there are two openings in ultrasonic sensor first is transmitter or trigger and second is receiver or echo.
The stick uses ultrasonic sensors for obstacle detection.
Smart blind stick with ultrasonic sensor abstract.
The smart stick is built on arduino pro mini.
Sometimes even when they use this stick there is no guarantee that the blind persons are safe and secured in.
The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing.
The technology can indeed neutralize human disability.
An ultrasonic sensor will be installed in a stick which will sense the distance of a person from any obstacle an ldr to.
We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology.
I used ultrasonic sensor for detecting the obstacles.
With this in mind let us use the power of arduino and simple sensors to build a blind man s stick that could be a lifesaver for visually impaired persons.
The blind stick is integrated with ultrasonic sensor along with light and water sensing.
