Abstract:
The presented research shows how advanced wireless
sensor technology can be used by engineers to monitor
conditions in and around buildings. The objective is
split into three different tasks. First, wireless sensor
hardware is programmed to process signals from sensors
and transmit the data in a suitable format. This task
was accomplished through an open-source operating system
and a programming language designed specifically for
wireless sensor hardware. The second task involved the
processing of signals sent by the wireless sensor nodes.
In this application, a Java program was written that
deciphered messages transmitted from a wireless receiver
over a computer's serial port and then placed the data
in a database. The structure of that database is
discussed to help identify the key pieces of information
that are needed to make use of the data. The third piece
of the proposed monitoring system is an interface to
review the data. A Web-based system was developed that
allows a user to mine the database using parameters such
as the type of data, location of sensor, and the time of
data acquisition. It is anticipated that this research
will demonstrate the potential of using wireless sensor
networks for monitoring buildings.
