Smart Blind Stick With Ultrasonic Sensor Abstract

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.

Smart blind stick with ultrasonic sensor abstract. An ultrasonic sensor is used for object. The stick uses ultrasonic sensors for obstacle detection. An ultrasonic sensor will be installed in a stick which will sense the distance of a person from any obstacle an ldr to. Blind stick is an innovative stick designed for visually disabled people for improved navigation.

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. Person suffering from night blindness cataracts glaucoma albinism or injury. The main aim of this project is to assist the blind persons without the human need. It cost me just 10 to make one.

The stick also has an rf receiver which connects with an rf transmitter that acts as a remote for finding the stick on missing. 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 smart stick is built on arduino pro mini. Presented here is a smart stick using arduino uno.

It is well known that the blind people carry a hand stick with them whenever they need a support. I used ultrasonic sensor for detecting the obstacles. Smart blind stick with ultrasonic sensor abstract. Through this the blind person can aware about the obstacles in front of him.

Obstacle detection is one of the major concerns for a fully or a partially blind person e g. 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. The blind stick is integrated with ultrasonic sensor along with light and water sensing. This paper reviews the design of a smart cane i e a smart stick for the blind equipped with obstacle recognition using ai technologies adds more virtual.

We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology. 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. Sometimes even when they use this stick there is no guarantee that the blind persons are safe and secured in. 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.
