IoT Based Smart Blind Stick Using GPS and GSM Module

Abstract

It is unsafe for visually challenged people to move on a busy road. It may lead to some accidents, when they get some obstacles on their way and are not able to identify them, which may not be known to their parents or guardians. Without having some kind of navigator, it is challenging for such people to navigate their surroundings and commute. Hence, we propose an IOT based navigating solution, the smart blind stick equipped with an ultrasonic distance sensor to identify obstacles and also the GPS system to help their parents and guardians to know their location. GSM module is used to send SoS messages to particular people in case of emergency. The smart blind stick is a tool for defining their environment. Smart Stick, ensures the security and effective mobility of visually challenged people. This is useful to avoid abstractions and help them in easy commuting and to send emergency message alerts.
