IOT Based Route Navigation System for Visually Impaired

Abstract

The IOT device dependent on ultrasonic sensors and Arduino for visually impaired. There are approximately 1 billion peoples over the globe who are visually impaired by the World Health Organization (WHO-2018) [2]. People with visual impaired are frequently reliant on outside help which can be given by people, trained dogs, or exceptional electronic devices as emotionally supportive networks for basic leadership. Therefore, we were motivated to build up a smart IOT device to overcome these limitations. We proposed a low cost and lightweight system designed with a microcontroller that processes the signal and alerts the visually impaired person over any obstacle through beeping sounds. The framework comprises of obstruction recognition sensors for accepting, handling and sending signals to the alarm system which at last alerts the client for brief activity. The framework was structured, programmed utilizing C++ language and tried for exactness and checked by the outwardly disabled individual. Our device can detect obstacles within the distance of about 20cm. This paper describes the working of a Blind Stick dependent on a microcontroller ATmega328 (Arduino Uno). We also used a GPS to monitoring the visually impaired for knowing his location to his family. By using this GPS tracking system his family can continuously get update location of that people via server or android apps. The latitude and longitude will automatically have added on database and then it’s can visible to his family. If unfortunately, the blind people fall in danger or any problem then he can use an alarm button so that his family can noticed that. When he/she press the alarm button then the sounds to his family
