Blind Stick Using Ultrasonic Sensors

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 stick using ultrasonic sensors.

The ultrasonic sensor detects obstacles and ldr sensor allows determining the lighted and dark places. Ultrasonic blind stick for completely blind people to avoid any kind of obstacles abstract. Ultrasonic blind walking stick components used. Blind walking stick arduino ultrasonic sensor.

Ultrasonic navigation system for the blind submitted by abhishek dixit gagandeep singh mohit kumar pravin kumar under guidance of prof. The technology can indeed neutralize human disability. To design blind walking stick using. 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. Sensor based blind stick 1. 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. Ultrasonic sensor is connected to arduino.

As shown in diagrams there are two openings in ultrasonic sensor first is transmitter or trigger and second. All the feedbacks will be given to the blind man through a buzzer. 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. 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.

Mishra head of department prof. Blind walking stick using arduino ultrasonic sensor hc sr04 blind walking stick using arduino ultrasonic sensor hc sr04. 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.

Abdul kalam technical. On sensing obstacles the sensor passes this data to the microcontroller.
