IOT Based Smart Stick with Voice Module

This project presents the smart idea to assist the blind persons without the human need. It is known that the blind carry a stick with them whenever they need the support. Even they carry a stick with them there is no guarantee that they are safe and secured in reaching their required places. Even if there may be an obstacle in their path but it may not noticed by the person with the help of the normal hand stick. Due to this the blind may be injured if the obstacle is dangerous. To avoid this problem, a smart stick comes as a proposed solution. Here we are using ultrasonic sensors to find any obstacles in front of the blind. If any obstacle is detected, voice messages alerts the blind. This system uses NodeMcu and GPS to track the blind.  The entire controlling unit is fixed to the hand stick. If any obstacle comes in front of blind person, they can easily get to know about the obstacle through the audio generated by the voice module and the location of blind people can be known by passing the information into cloud using IoT.
