An IoT-based smart blind stick is a tool that helps people with visual impairments navigate their surroundings by using sensors, microcontrollers, and wireless connectivity. The Internet of Things (IoT) technology, which involves tying machines, sensors, and gadgets to the internet in order to gather and process data, is the foundation around which this device is built.
 
The smart blind stick uses a variety of sensors, including infrared and ultrasonic ones, to measure distances and detect obstacles. These sensors provide data to a microcontroller, which interprets the data and gives feedback to the user using algorithms and machine learning. Additionally, the device can be linked to a smartphone application, which enables users to modify the feedback and get extra details like GPS location and weather.
 
By enabling visually impaired people to navigate their surroundings with more ease and confidence, an IoT-based smart blind stick can dramatically increase their independence and safety. The technology has the power to completely change how people who are visually impaired interact with their surroundings, making daily activities more pleasurable and accessible.
