Blind Stick Using Ultrasonic Sensors

Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves.

Blind stick using ultrasonic sensors.

Smart blind stick project using arduino and sensors. The blind stick is integrated with ultrasonic sensor along with light and water sensing. Ultrasonic sensor is connected to arduino. Ultrasonic navigation system for the blind submitted by abhishek dixit gagandeep singh mohit kumar pravin kumar under guidance of prof.

In the circuit an arduino nano is used as the platform. On sensing obstacles the sensor passes this data to the microcontroller. 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. 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.

In this project we will learn how to design blind. 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. Blind walking stick arduino ultrasonic sensor. Abdul kalam technical.

To design blind walking stick using. Ultrasonic blind walking stick components used. Gangwar project incharge department of electronics engineering kamla nehru institute of technology sultanpur 228118 u p dr. The technology can indeed neutralize human disability.

Ultrasonic blind stick for completely blind people to avoid any kind of obstacles abstract. As shown in diagrams there are two openings in ultrasonic sensor first is transmitter or trigger and second. Mishra head of department prof. The ultrasonic sensor detects obstacles and ldr sensor allows determining the lighted and dark places.

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. All the feedbacks will be given to the blind man through a buzzer.
