An Intelligent and Multi-Functional Stick for Blind People Using IoT

The primary goal of this study is to aid blind people who do not require human assistance. People who cannot see the world have difficulty perceiving the obstacles in front of them, putting their lives in jeopardy. Using an intelligent and multipurpose bright blind stick will allow them to recognize their environment. In this study, we presented a low-cost, innovative, and versatile stick for blind individuals in our community adopting IoT to better their lives. A person can walk more confidently with the help of this brilliant blind stick. This stick can identify impediments in the route of blind people thanks to an Arduino UNO, ultrasonic sensor, IR sensor, water sensor, GPS and GSM modules, four-channel wireless remote control, and Buzzer. This stick identifies any object or barrier in front of the user, such as water, holes, stairs, or cars, and if any are detected, the system will inform the blind person via a buzzer. Our system’s processing unit, the Arduino UNO, processes all input and delivers outputs. The walking stick has an ultrasonic sensor and an infrared sensor to identify obstructions in front of blind or disabled people. The water sensor can detect the presence of water and emit an alarm to inform people who are blind. Friends and family members of blind people may easily monitor them using our technology, and blind people can also use GPS and GSM to locate the stick by pressing a button on the remote, which will cause the Buzzer to ring continuously for 5 seconds, indicating its location. We also researched and compared various current systems in this study, which led us to build a cost-effective, quick-responding, portable, intelligent, and bright multipurpose stick for blind persons utilizing IoT.
