IOT Innovation And Sustainability For Smart Blind Stick With GPS Tracker (GF-21), Ultrasonic Sensor To Detect An Object And For Distance Measuring Using Bluetooth (HC- 05) Wireless Via Smartphone Based On IR Project Using Arduino UNO R3 For The Blind.

Abstract

This project was developed as see there are no initiative for blind person to make them feel save when they walk outside without guardians. The life of blind people is very difficult and challenging, they can’t see an object in front them and sometimes they can get hit by object even human and it actually can lead to injured. The Smart Blind Stick is intended to help reduce the difficulties faced by blind people. The Smart Blind Stick will be embedded by sensor to senses any object or human in front of them.Besides that, the tendency to blind people get lost is very high because they can’t see the road. With that use GPS (GF-21) to track where they go and this stick will inform the keeper the current location whenever they go to anywhere. Nextly, with the measuring device used by the blind. The keeper can know the distance of an object in front of the Smart Blind Stick while the blind person uses the Smart Blind Stick to keep the safety of the blind person from the momentum that is in front. This is in the presence of assistive devices such as Ultrasonic Sensors to measure the distance using Bluetooth (HC-05) wirelessly via a mobile phone to a Serial Bluetooth Terminal Application. Visually impaired people are faced with a lot of problems in their daily life due to their inability to see and move around. These individuals are ultimately dependent on others for assistance, or they may use a trained dog to help them navigate as they travel outdoors. This problem has motivated the development of the smart stick with the aim of providing a better alternative to assist the visually impaired. This is achieved by novel connection of an Ultrasonic Sensor and a Buzzer. When The Smart Blind Stick senses an obstacle, the Buzzer activated, the Led activated and the user is alerted. The alert is in the forms of sound and vibration from the Buzzer . The system is designed and programmed using Arduino UNO R3 programming language. With the help of the proposed novel technology, the visually impaired individual can live independently and move freely, easily, and safely without any assistance required. After some rigorous tests, the system is proven to be efficient and cost effective.
