Ultrasonic Sensor For Blind Person

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

Ultrasonic sensor for blind person.

The ldr circuit coupled with led lets other people and vehicles aware about the blind person in the dark. 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 all the feedbacks will be given to the blind man through a buzzer. 5 designed the handheld device for obstacle detection using ultrasonic sensor and generate voice alert for blind and vibration alert for deaf person by keeping his finger. 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.

An ultrasonic range sensor is used to detect surrounding obstacles and electronic compass is used for. Using the five ultrasonic sensors blind people can detect the objects in a five dimensional view around them and can easily travel anywhere. We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology. Using ultrasonic sensor for blind and deaf persons combines voice alert and vibration properties research journal of recent sciences 2012.

An ultrasonic navigation system for blind people. Blind people who use the seeing eye dog or the white cane should not use elastic bands otherwise sensors will detect the white cane or seeing eye dog as an obstacle. When the ultrasonic sensor detects obstacle the device will notify the user through vibrations and sound beeps. The intensity of vibration and rate of beeping increases with decrease in distance and this.

12 10 shows the ultrasonic sensor present in the front side and it will detect the obstacle on the front side of the person and then it will send command to the controller. The ultrasonic sensors fitted with the system provides obstacle data to the blind person through voice message so that he she may avoid them. Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity. The white cane that they use when walking is used for helping them navigate the ground but does not do much for up above.

Using an arduino pro mini mcu ultrasonic sensor and a buzzer he created these glasses that will sense the distance of an object in front and beep to alert the person that something is in front of them. All the directions will be given to the blind man through a buzzer.
