Blind Stick, HCSR-04 Sensor, GPS Tracking, Internet of Things, Visual ImpairmentAbstract
Visual impairment can make it difficult for a person to carry out daily activities. An innovasion in walking stick is a huge imrovement to overcome this problem. This research uses the research and development method by testing the accuracy of the sensors and the reliability of the device consisting of NodeMCU ESP-8266 as the microcontroller, HCSR-04 Sensor for object reading which is equipped with an output in the form of DFPlayer as a notification from the HCSR-04 sensor, and GPS Sensor to determine the presence of the device and then monitoring through the Blynk application installed on the user's smartphone. The results of the following research are in the form of hardware and applications that are able to provide information related to user coordinates that can be monitored from different locations with the help of the Internet of Things
