Introduction

In an effort to improve the quality of life of people with visual impairments, this research proposes the design of distance measuring aids that use ultrasonic sensor technology. The proposed tool consists of a pair of ultrasonic sensors that function to detect distances by emitting and receiving ultrasonic signals. The AT89S51 microcontroller is implemented as the brain of this system, which will calculate the time between the emission and receipt of the signal. The measurement results of the distance will be delivered through alarm, so that people with visual impairments can find out the existence of the object in front of them. By utilizing the speed of sound, this tool is expected to be able to provide the information needed for daily navigation.

System Design Analysis

Ultrasonic Sensor Technology

Ultrasonic sensor technology is a tool that is widely used in various distance measurement applications due to its accuracy. The way this sensor works is very simple: When the ultrasonic signal is emitted, it will bounce back after it hits the object in front, and the time required to return to the sensor is calculated to determine the distance. This sensor has advantages in terms of safety, because it does not use dangerous radiation and can work well in various environmental conditions. The use of ultrasonic sensors in this project is a significant advantage, as it provides a reliable and accurate method for measuring distances.

AT89S51 Microcontroller

With the right programming, this microcontroller can be adjusted to calculate the delay time very accurately, allowing the distance measuring system to work efficiently. In addition, this microcontroller is also relatively cheap and easy to integrate with other components, such as alarm that will sound when a certain distance is detected. The use of the AT89S51 microcontroller in this project is a cost-effective solution, as it provides a reliable and efficient method for calculating distances.

Alarm as a Telling

The importance of the alarm system in this tool cannot be ignored. Alarm functions as an indicator for blind people that there are objects near them. By utilizing the tone of voice or vibration, this tool will provide a clear and easy to understand signal. This is very helpful for users in interacting with the surrounding environment, so they can move more confidently and safely. The use of an alarm system in this project is a significant advantage, as it provides a clear and easy to understand method for indicating the presence of objects.
