Abstract

This paper presents a design and analysis of ultrasonic sensing system for visually impaired person. This system operation consisting of ultrasonic sensor and a microcontroller as the brain for the system. The experimental measure been done to calibrate the sensor to produce accurate measurement of distance. Basically, the prototype device produce is a portable device which can be kept in user’s front pocket or can be wear using lanyard. Device will assist the user according to the range of obstacle. Whereby the user is closer to an obstacle the connected buzzer will beep at different rate according to the range of the obstacle. The project is designed and developed using P18F1330 microcontroller and programmed using C language.
