Blind Stick Using Ultrasonic Sensors

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.

Blind stick using ultrasonic sensors.

The ultrasonic sensor detects obstacles and ldr sensor allows determining the lighted and dark places. In the circuit an arduino nano is used as the platform. On sensing obstacles the sensor passes this data to the microcontroller. Gangwar project incharge department of electronics engineering kamla nehru institute of technology sultanpur 228118 u p dr.

Smart blind stick project using arduino and 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. Sensor based blind stick 1. Blind walking stick using arduino ultrasonic sensor hc sr04 blind walking stick using arduino ultrasonic sensor hc sr04.

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. 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. Ultrasonic navigation system for the blind submitted by abhishek dixit gagandeep singh mohit kumar pravin kumar under guidance of prof.

Blind walking stick arduino ultrasonic sensor. To design blind walking stick using. Ultrasonic sensor is connected to arduino. The blind stick is integrated with ultrasonic sensor along with light and water sensing.

Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. In this project we will learn how to design blind. The technology can indeed neutralize human disability. Ultrasonic blind stick for completely blind people to avoid any kind of obstacles abstract.
