Physically disabled people like blind are sensitive to getting in contact with whatever obstruction which might pass by them while performing daily activities like walking, subjecting them to the threat of injury due to falling and it could also cause great damage to them. The target of our project is to develop a smart walking aid with measurement of distance from obstacles in front of them using IoT and it is compatible with Blind-dumb-deaf. In our project we are enriching the stick with a variety of sensors. The stick contains ultrasonic sensors for distance measurement. In the project, pulse sensor and temperature sensor continuously checks pulse and body temperature and Vibration motor is used as a secondary output. OLED will display the data and it helps the deaf to seek help. Raspberry Pi microcontroller processes the information which later produces a voice for alerting the blind person as the output. GPS live tracking systems will be used to track the blind people. Overall, the system notifies the hurdles to the vision-impaired through the auditory output through which they can walk safely without any problem. The details will be stored in Google Firebase and the data will be monitored using an Android app.
