Description

Abstract

This system was proposed as an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology. Our proposed project 1st uses ultrasonic sensors to detect obstacles ahead using supersonic waves. The microcontroller then processes this information and calculates if the obstacle is close enough. If the obstacle isn’t that shut the circuit wills nothing. If the obstacle is shut the microcontroller sends a signal to sound a buzzer. It additionally detects and sounds a unique buzzer if it detects water and alerts the blind. An extra feature is that it allows the blind to sight if there’s light or darkness within the room. A wireless RF-based mostly remote is used for this purpose. Pressing the remote button sounds a buzzer on the stick that helps the blind man to search out their stick. Therefore this system allows for obstacle detection yet as finding stick if misplaced by visually disabled people.

Proposed System

The mostly blind person affected by the normal person. In this system, we have used the ultrasonic sensor, moisture sensor, and light sensor. If any abnormal buzzer will blow and blind person forget the stick means RF module will help them to find the stick.
