Smart Guidance Belt for Blind People

Description

DESCRIPTION

In this project the ultrasonic sensors are mounted on the belt and emit sound waves that bounce off objects in the vicinity. The sensors then measure the time it takes for the sound waves to return, allowing the belt to calculate the distance to nearby obstacles.The ISD1820 voice module converts this distance data into audible instructions or feedback, which is relayed to the user through a set of earphones or a small speaker. The belt might say “Obstacle detected 2 meters ahead or Clear path detected.The Smart Guidance Belt aims to enhance the blind person’s awareness of their environment, enabling them to avoid obstacles and navigate safely.
