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.
