Blind Stick Using Ultrasonic Sensors

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

Blind stick using ultrasonic sensors.

Ultrasonic sensor is connected to arduino. Blind walking stick arduino ultrasonic sensor. Blind walking stick using arduino ultrasonic sensor hc sr04 blind walking stick using arduino ultrasonic sensor hc sr04. Ultrasonic navigation system for the blind submitted by abhishek dixit gagandeep singh mohit kumar pravin kumar under guidance of prof.

On sensing obstacles the sensor passes this data to the microcontroller. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. The ultrasonic sensor detects obstacles and ldr sensor allows determining the lighted and dark places. Abdul kalam technical.

To design blind walking stick using. Gangwar project incharge department of electronics engineering kamla nehru institute of technology sultanpur 228118 u p dr. 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. Smart blind stick project using arduino and sensors.

Mishra head of department prof. Ultrasonic blind stick for completely blind people to avoid any kind of obstacles abstract. Ultrasonic blind walking stick components used. All the feedbacks will be given to the blind man through a buzzer.

In the circuit an arduino nano is used as the platform. Sensor based blind stick 1. 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. In this project we will learn how to design blind.

As shown in diagrams there are two openings in ultrasonic sensor first is transmitter or trigger and second. The technology can indeed neutralize human disability.
