Blind Stick Using Ultrasonic Sensors

The remote built on rf transmitter has a switch pressing which the buzzer installed on the stick is triggered and by the sound of the buzzer a blind person can find the stick.

Blind stick using ultrasonic sensors.

Ultrasonic navigation system for the blind submitted by abhishek dixit gagandeep singh mohit kumar pravin kumar under guidance of prof. 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. The technology can indeed neutralize human disability. Gangwar project incharge department of electronics engineering kamla nehru institute of technology sultanpur 228118 u p dr.

Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. Blind walking stick arduino ultrasonic sensor. The blind stick is integrated with ultrasonic sensor along with light and water sensing. In this project we will learn how to design blind.

The ultrasonic sensor detects obstacles and ldr sensor allows determining the lighted and dark places. Blind walking stick using arduino ultrasonic sensor hc sr04 blind walking stick using arduino ultrasonic sensor hc sr04. Smart blind stick project using arduino and sensors. Ultrasonic sensor is connected to arduino.

Ultrasonic blind stick for completely blind people to avoid any kind of obstacles abstract. Sensor based blind stick 1. Ultrasonic blind walking stick components used. An ultrasonic sensor will be installed in a stick which will sense the distance of a person from any obstacle an ldr to sense lighting conditions and an rf remote which the blind man could use to remotely locate his stick.

To design blind walking stick using. The ability to live without being controlled by any action judgment and any outside factors including any opinions and regulations is defined by the term independent. All the feedbacks will be given to the blind man through a buzzer. As shown in diagrams there are two openings in ultrasonic sensor first is transmitter or trigger and second.

In the circuit an arduino nano is used as the platform. Mishra head of department prof.
