Abstract

This project is to build a device that can find range between two objects by using ultrasonic sound wave. Ultrasonic sound wave is cyclic sound pressure with a frequency greater than the upper limit of human hearing. Ultrasonic wave will control and generated by PIC 16F88 microcontroller. It will send through the transmitter and the pulse reflects off an object and is re-::eived by receiver. The time from transmission to reflect sound reception lets calculate the dist:.nce from the object. Transducer were ~.1sc to convert sound signal wave from digital to analog signal and vice versa. The result of distance will display on the Liquid Crystal Display (LCD). This device can find range up to 3 meter using 40KHz transducer and 4 MHz internal oscillator frequency. Normally, distance can be found by used standard device like mler and meter tape but sometimes this device is not relevant in some situations like to find range between two cars while this car is moving. Main objectives of this project is to build a device (using PIC 16F88) that can measure the distance between two objects by using ultrasonic sound wave and display result of distance on LCD display. With high frequency ultrasonic sound wave that been used, it's should be no problem to get result of distance up to 3 meter. Accuracy of this device is ± 3 em. This accuracy depend to the error that will be faced from the others sound wave noise of the environment while using this devices. The software mikroC and Proteus Virtual System Modeling (VSM) was used to make programming and circuit for simulation. The Ultrasonic Range Finder device is developed and validated, it can measure distance up to 3 meter by using ultrasonic sound wave and display the result on the LCD panel.
