Rf transmitter and receiver the stick is also equipped with light dependent resistor ldr sensor and an ultrasonic sensor informs sajal.
Smart blind stick with ultrasonic sensor documentation.
Smart blind stick using arduino with ultrasonic sensor and ir sensor 28.
The smart stick is built on arduino pro mini.
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.
He has named this stick as smart blind stick.
Ultrasonic sensor 2 buzzer led should be attached to breadboard then we should connect these components to arduino by wires after that the circuit should be attached to a stick with a tape.
For better accuracy and assistance two or three ultrasonic sensors sensors can be added to this project.
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.
Obstacle detection is one of the major concerns for a fully or a partially blind person e g.
Smart blind stick with ultrasonic sensor documentation 26.
Person suffering from night blindness cataracts glaucoma albinism or injury.
The technology can indeed neutralize human disability.
Smart blind stick using.
Smart blind stick with gps 27.
The blind stick is integrated with ultrasonic sensor along with light and water sensing.
An ultrasonic sensor will be installed in a stick which will sense the distance of a person from any obstacle an ldr to.
Presented here is a smart stick using arduino uno.
We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology.
These blind people are totally dependent on others as they can t walk alone.
Blind stick is an innovative stick designed for visually disabled people for improved navigation.
This smart stick can help blind people walk on the street safely without any help.
The stick uses ultrasonic sensors for obstacle detection.
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.
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.
