Abstract

The main purpose of this project is to help the blind person to visualize the current situation for ensure them from hitting the obstacle or fallen while walking. Admit that, there has a blind stick for helping the blind person but it is a traditional blind stick and need to improvise for help blind person. Furthermore, the traditional blind stick has a limitation which is to notify the user about the presence of obstacle and water. Besides that, this project come out with the sensor at head level. It is design to avoid blind person hit the obstacle at head level such as branch or wall. The sensor at head level, are implement at a hat and will be wear by blind person. The sensors that will be used in this project are ultrasonic sensor and water sensor. Ultrasonic sensor is used to measure the distance between blind stick and obstacles. Then water sensor, used to detect the presence of water at ground. Arduino UNO is used for interfacing between hardware part and software part which is program coding for a project. For software part, Arduino IDE will be used to place the program and implement it to the microcontroller on Arduino UNO. For notification part, buzzer and vibrator will be used for notify the blind person about the current situation. The buzzer will be sound at a different frequency according to sensor detection.
