Smart Blind Stick With Ultrasonic Sensor

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. 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.

The blind stick is integrated with ultrasonic sensor along with light and water sensing.

Smart blind stick with ultrasonic sensor.

The smart stick is built on arduino pro mini. Through this the blind person can aware about the obstacles in front of him. We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology. 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.

Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity. For better accuracy and assistance two or three ultrasonic sensors sensors can be added to this project. I used ultrasonic sensor for detecting the obstacles. Blind stick is an innovative stick designed for visually disabled people for improved navigation.

It cost me just 10 to make one. 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 is the reason why we have designed the blind walking stick device which will help blind people to walk with ease independently.
