Smart Cane for Blind People using Raspberry PI and Arduino

2020 International journal of recent technology and engineering  
In this paper we are introducing a stick to guide blind people to move independently. It consists of raspberry pi and Arduino for monitoring the stick. Three pairs of ultrasonic sensors are used to detect obstacle in front of the users in the range of 15cm, and water sensors are used for water detection & puddles. The above sensors are interfaced in the stick. The stick can take robotic decision to move forward, backward, left and right as per obstruction detection using dc motor. Users will

Finger ring is used to give navigation using GPS. The user can maintain easily with fast response & low power consumption The main purpose of this paper is to help visually impaired people for navigating independently
