Tredimensionell sensorscanner

Abstract

This report is a bachelor thesis presented at the department of Computer Science and Engineering at Chalmers University of Technology. The aim for the project is to find a simple method to measure and display physical quantities in a three dimensional room. The report describes a method to construct a system for measuring different physical quantities via sensors. The system must be built in a modular and expandable way to be adaptable to different tasks. The system explained in the report consists of two parts; A physical scanner with moveable probes for carrying sensors and a microcontroller for controlling the probes and communicating with the next part. An application written in Java for storing the measured values and presenting them in a lucid perspective. It is possible to construct the scanner with different designs and circuitry, with multiplexers and flip-flops, to ensure that an unspecified number of probes can be added to the system and that they can be operated simultaneously. The Java application is written in a modular way, using a design pattern that separates each individual part of the application. It contains exceptions and interfaces that ensure a safe and expandable application.
