INTRODUCTION
The focus of this research project was to incorporate wireless sensor
networks to remotely monitor an artificial aquatic ecosystem and to
establish a method of collecting data for pH, temperature, and
dissolved oxygen. One of the major challenges with collecting
meaningful data in the field is the cost of the equipment used to
monitor aquatic environments. This cost is a barrier that can prevent
researchers from being able to deploy sensors in a dense enough
pattern to adequately monitor the environment and requires more
extrapolation and estimates back in the lab. As such, our design
needed to be low power and cost effective. The Research Experience
for Teachers provided a platform for us to expand our personal
understanding of electrical engineering and some of the difficulties
facing researchers in the field. By putting ourselves into a project
where we were forced to grow and learn in an area we were not
especially comfortable with allowed us to step out of our roles as
teachers and into the shoes of our students. That experience will
allow us to create more meaningful lesson plans to bring to our
classrooms.

The Xbee is a radio transmitter that is inexpensive and has solid support
and integration with the Arduino through a custom circuit board known as
a shield. The XBee uses the ZigBee protocol. Zigbee is a high level
communication protocol that complies with FAA rules for private
transmission. It is designed for applications that do not have a demand for
high bandwidth and that need to function in low power systems. Zigbee
utilizes a mesh network layout that allows the radios to form ad hoc
connections and transmit their data along that web rather than relying on
one high power transmitter in the center of the network that is able to
reach all the radios.
Atlas has the advantage of providing all three types of probes that are
intended to integrate into the sensor cluster: pH, temperature and
