This paper presents design and implementation of an ultrasonic sensor based walking stick for visually impaired person. An ultrasonic sensor module, HC-SR04 is used for obstacle detection in the path of the blind person and a buzzer is used to make the person alert. The proposed system is implemented using Raspberry Pi microcontroller. Blind persons can use this walking stick for safe navigation. It can detect obstacle within 5 to 35 cm range of distance.This model has been successfully developed with the concept of Internet of Things [IoT] by integrating necessary sensors and Raspberry Pi.
