Smart Blind Cap using Ultrasound Distance Measurement Sensor System

Abstract

There are blind people in nearly all nations of the world. We have many blind people in Bangladesh. Many problems have to be overcome in their drive. We have ongoing this ultrasound device scheme caps for them. Sightlessness is a national of missing the graphic vision due to physical or courage issues. In this work, a humble, inexpensive, friendly user, smart blind control system is intended and understood to meeting the action of calm blind and visually abridged people in a careful area. The smart blind cap using ultrasound taciturnity length sensor system to help the blind person to steer alone firmly and to avoid any problems that may be hostility, whether fixed to stop any likely chance. The main constituent of this system is the ultraviolet sensor which is used to image a prearranged area about blind by producing-shiny waves. The reproduced signals received from the wall objects are used as inputs to PIC 16F72 microcontroller. The microcontroller is then used to control the way and distance of the matters about the blind. We also use a shake motor that shake when the blind person come to the problem very near. The applied system is inexpensive, fast, and informal to use and an advanced reasonable solution to blind.
