Smart Blind Stick With Ultrasonic Sensor Documentation

An ultrasonic sensor will be installed in a stick which will sense the distance of a person from any obstacle an ldr to.

Smart blind stick with ultrasonic sensor documentation. Obstacle detection is one of the major concerns for a fully or a partially blind person e g. He has named this stick as smart blind stick. Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity. Smart blind stick with gps 27.

This is the reason why we have designed the blind walking stick device which will help blind people to walk with ease independently. Person suffering from night blindness cataracts glaucoma albinism or injury. This smart stick can help blind people walk on the street safely without any help. 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 smart stick is built on arduino pro mini. The stick uses ultrasonic sensors for obstacle detection. For better accuracy and assistance two or three ultrasonic sensors sensors can be added to this project. 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.

The blind stick is integrated with ultrasonic sensor along with light and water sensing. Rf transmitter and receiver the stick is also equipped with light dependent resistor ldr sensor and an ultrasonic sensor informs sajal. 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. 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 with ultrasonic sensor documentation 26. 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. The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing. These blind people are totally dependent on others as they can t walk alone.

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. Smart blind stick using arduino with ultrasonic sensor and ir sensor 28. Smart blind stick using. Blind stick is an innovative stick designed for visually disabled people for improved navigation.
