| Summary: | This chapter discusses the use of unattended sensors and its use in marine environment. The authors
present challenges of designing a marine sensor in harsh environments and a case study in implement-
ing a marine sensor to study hypoxia. Hypoxia is a world-wide anthropogenic phenomenon related to
pollution. The authors describe the construction of an inexpensive sensor buoy system, Oxybuoy, de-
signed for long-term unattended oxygen sensor measurements. The technology is available to construct
such sensor buoys. The authors showed a prototype based on commercial off-the shelf components:
an embedded PC, an optical dissolved oxygen sensor, a temperature sensor, a Wi-Fi transmitter and a
satellite transmitter. Its total cost is around $5,000 to construct, program and test a proof of concept of
such sensor. The authors describe the buoy’s architectural design and three experiments that the authors
carried out to demonstrate its viability. |
