AbstractThe greatest gift for appreciating nature is the eye. Blind persons have many challenges in their daily lives. People who are blind must rely on others to carry out their daily tasks. With the emergence of artificial intelligence, the internet of things, wireless sensor networks, and other innovations, information technology is revolutionizing every aspect of existence. The Internet of Things is a rapidly developing technology that connects people, machines, sensors, and everything else digitally for automation. The visually challenged can be assisted using an IoT-based smart blind stick that has a navigation system. A buzzer and ultrasonic sensor are built inside the smart stick to detect obstacles and sound a warning. Using a smart stick and a GSM module, registered numbers can receive critical notifications and GPS locations. This is an economical solution.
