Smart Blind Stick With Ultrasonic Sensor Pdf

Presented here is a smart stick using arduino uno.

Smart blind stick with ultrasonic sensor pdf.

Thus the obstacleswhich are in front can. The smart stick is built on arduino pro mini. The stick uses ultrasonic sensors for obstacle detection. Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity.

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. 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 blind stick is integrated with ultrasonic sensor along with light and water sensing. An ultrasonic sensor is used for object detection from a variable distance and a vibration actuator is attached with the handle of the stick to provide vibration feedback to the user depending.

Smart blind stick project using arduino and sensors. A number of techniques for making a smart stick for blind people. Blind walking stick using arduino ultrasonic sensor hc sr04. In this project we will learn how to design blind walking stick using arduino ultrasonic sensor hc sr04.

These blind people are totally dependent on others as they can t walk alone. The ultrasonic sensors work efficiently in an angle of 45 degrees. 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. 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. Almost 30 million people are blind according to the recent who report. Blind stick is an innovative stick designed for visually disabled people for improved navigation. Person suffering from night blindness cataracts glaucoma albinism or injury.
