Ultrasonic Sensor For Blind Person

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.

Ultrasonic sensor for blind person.

The blind stick is integrated with ultrasonic sensor along with light and water sensing. 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. Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity. Blind stick is an innovative stick designed for visually disabled people for improved navigation.

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. The ultrasonic sensors fitted with the system provides obstacle data to the blind person through voice message so that he she may avoid them. All the directions 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.

The intensity of vibration and rate of beeping increases with decrease in distance and this. 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. The ldr circuit coupled with led lets other people and vehicles aware about the blind person in the dark. Using ultrasonic sensor for blind and deaf persons combines voice alert and vibration properties research journal of recent sciences 2012.

If a blind person faced any obstacle in his way then the beep sounds alert him for the obstacle so he can change his path. 3 regalado melo rosa. 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 the five ultrasonic sensors blind people can detect the objects in a five dimensional view around them and can easily travel anywhere.

An ultrasonic range sensor is used to detect surrounding obstacles and electronic compass is used for. 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.
