Smart Blind Stick With Ultrasonic Sensor Using Arduino

These blind people are totally dependent on others as they can t walk alone.

Smart blind stick with ultrasonic sensor using arduino.

The stick uses ultrasonic sensors for obstacle detection. Using this smart blind stick a visually impaired person can walk without anyone s help. The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing. Person suffering from night blindness cataracts glaucoma albinism or injury.

An ultrasonic sensor will be installed in a stick which will sense the distance of a person from any obstacle an ldr to. 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. Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity. 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.

Blind walking stick using arduino ultrasonic sensor hc sr04. The smart stick is built on arduino pro mini. Almost 30 million people are blind according to the recent who report. I used a mini breadboard to connect the ultrasonic sensor to the arduino using.

Ultrasonic sensor 2 buzzer led should be attached to breadboard. 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. 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. Presented here is a smart stick using arduino uno.

This smart stick can help blind people walk on the street safely without any help. The technology can indeed neutralize human disability. 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. Obstacle detection is one of the major concerns for a fully or a partially blind person e g.
