Abstract

The purpose of this project is to design and develop a system that can be used to measure distance in order to make the measurement process easier without any hazard, wasting the energy and time. This portable distance measurement used the reflection concept. In this system, the distance will be measured by transmit ultrasonic and infrared wave to the object and then the wave reflect back to receiver. After the receiver received the reflected wave, the system will calculated and then display the distance on the Liquid Crystal Display (LCD). In detail, the data (input) will be collected from the Infrared and Ultrasonic sensors as an analog voltage. And then the analog voltages will calculated and then convert it to digital binary using Analog to Digital Converter (ADC) that built-up in PIC16F877A as converted data (output) of the system before display the distance on the Liquid Crystal Display (LCD). For this project, the measurement distance target is less than 1 meter. The sensors that were used for this project are infrared and ultrasonic sensor. The main objective for this project is to measure exactly the distance from system to the target.
