Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity.
Smart blind stick with ultrasonic sensor documentation.
This is the reason why we have designed the blind walking stick device which will help blind people to walk with ease independently.
Smart blind stick with ultrasonic sensor documentation 26.
The smart stick is built on arduino pro mini.
Rf transmitter and receiver the stick is also equipped with light dependent resistor ldr sensor and an ultrasonic sensor informs sajal.
The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing.
For better accuracy and assistance two or three ultrasonic sensors sensors can be added to this project.
This smart stick can help blind people walk on the street safely without any help.
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.
An ultrasonic sensor will be installed in a stick which will sense the distance of a person from any obstacle an ldr to.
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.
These blind people are totally dependent on others as they can t walk alone.
The stick uses ultrasonic sensors for obstacle detection.
Smart blind stick with gps 27.
He has named this stick as smart blind stick.
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.
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.
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.
Smart blind stick using.
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.
The blind stick is integrated with ultrasonic sensor along with light and water sensing.
Blind stick is an innovative stick designed for visually disabled people for improved navigation.
The technology can indeed neutralize human disability.
