Abstract

This project is about designing an ultrasonic parking range meter using programmable interface controller (PIC) microcontroller system, sensor and several other devices. Ultrasonic parking range meter is a device that measuring the range between vehicle and wall when the vehicle is reversing. Ordinary device only using sensor and produce bleeping sound when the vehicle is too near to the wall. This project is created to improve this ordinary device to ensure people are not mistaken in judging their vehicle and the wall range to avoid crashes. This project is using an ultrasonic receiver and transmitter while the range is shown by seven-segment LED display in centimeter unit. The receiver and transmitter are situated at the backside of the vehicle's bumper and its function is detecting if there's any object (wall) when reverse gear in place. Transmitter will produce ultrasonic to the wall, ultrasonic will turn back to receiver when it reaches the wall and ultrasonic receiver will send the data to PIC microcontroller to calculate the distance. The objective of this project is to avoid car crashes when backing up (parking). It is also an improvement for already used device which is bleeping sound when the vehicle is too near to the wall. Even tough sensor has many disadvantages to vehicles, but the advantages of using it is cheap, easy to manage, it allows meaningful conclusions to be drawn up about a person's lifestyle and how the system can benefit this. Tools can be developed to predict something undesirable before it actually happens.
