A Smart Glove Detection for Visually Impaired: Implementation of Ultrasonic and Flame Sensor

Abstract

The number of cases of blindness in Indonesia is very high. Almost 3.6 million blind people in Indonesia and 70% are having cataracts and the rest are blind due to several cases, such as an abnormality during pregnancy, a fatal accident, or a health problem that causes blindness. Furthermore, the author is very motivated to make a development which definitely aims to minimize something unwanted and unpredictable particularly for blind people. This project focused on the threat of fires that can occur at any time by conducting a smart glove that not only aims to detect distances or obstacles in front of the person, but the author will add several supporting components which of course can be used to detects if a fire occurs and can be immediately notified to the family. A smart glove uses Ultrasonic mode for helping the visual impaired or blind people. The result showed that by using buzzer, when the people were blocked by something or in any dangerous. Also, this project can be used for detect flames either small flame or larger flame and also send a message. So, the message will receive by their family when something happened by use flame detection mode. Later the results of this experiments can be proven that in objects with a distance of more than 40cm the buzzer does not sound, whereas if the object is close to 40 - 5 cm the buzzer will sound. This number was obtained during testing using both the acrylic box and the experimental use by the author's hand. For the results when testing the flame sensor and SIM800L, it can be stated that to detect this large fire the distance range is more or less 20 cm, while for small fires at a distance of more or less 15 cm. At the end of this final project, the author will show the results about how this smart glove worked, which can be seen from the table, figure, and link a video that has been included at this writing.
