Ultrasonic Blind Stick with GPS and GSM Tracking

Abstract

Abstract: In this project we are proposing to create a model which will act as a boon for the visually impaired people in our society. This study is trying to work over a hypothetical idea of a walking stick that would alert the visually challenged people on encountering an obstacle, holes and water in their vicinity which would help in preventing any kind of accidental injury to them while walking. The project visualizes the idea of a revolutionary navigation tool for the visually impaired people. This ordinary looking blind stick is actually extra ordinary it has been provided with different kind of sensors to give the person an idea about the vicinity in which he or she is present and make the individual much more aware. The GPS sensor has been designed and programmed in such a manner that is it is able to give an idea about the best possible route depending upon the location it is able to access. The user has been provided with the phenomenal feature of choosing locations from the set of destinations that have been stored in the database of the system. In this stick ultrasonic sensor GPS and GSM tracker, ESP 8266, water sensor, infrared sensor and RF sensor, battery have been used. the comprehensive goal of the device is to provide a much more comfortable and Secure method for the visually impaired people to overcome hindrances in daily life.
