The buoy features IoT sensors and is designed to take the “pulse” of a specific area of the ocean
Solar energy group Kyocera has provided four solar panels and a wind turbine to power an Ocean Internet of Things (OIoT) remote data monitoring platform, located off the coast of Huntington Beach, California.
Developed by eMarine Systems, the new Nomad sea buoy is designed to take the “pulse” of a specific area of the ocean. The buoy features IoT sensors that transmit a variety of marine data in real-time to the wireless cloud, providing government agencies, the scientific community and research institutions a web-based analysis of the ocean.
Nomad is an aluminum boat 10 feet wide and 20 feet long with equipment and batteries below deck. The 145W solar panels deployed have been tested for long-term deployment in marine and coastal areas. These along with a vertical axis wind turbine (VAWT) are supported by solar charge controllers and a battery monitor, which network together to provide power for the buoy’s functions.
“We selected Kyocera’s solar panels because they’re known for long-term reliability and quality,” said Bob Everhard, sales manager, eMarine Systems. “Knowing the panels have proven to withstand even the harshest coastal conditions ensures this innovative marine IoT solution will provide uninterrupted transmission of compelling data from the sea without costly and time-consuming maintenance issues.”
A Sea-Bird MicroCAT sensor on the buoy monitors water temperature, salinity, dissolved oxygen, phytoplankton density and sensor depth. Real-time cameras mounted to its mast will provide security for the 100-acre Catalina aquaculture ranch, and the buoy’s internal battery voltage and processor temperature are remotely monitored to help ensure optimal performance.
In the future, the buoy will measure pH levels and pings from acoustic tags placed on marine mammals by researchers. It will also feature additional above- and below-water live camera feeds.
Kyocera said its entire line of photovoltaic (PV) solar modules has passed the Salt Mist Corrosion Test, IEC 61701: severity level 6 and severity 1, administered by TÜV Rheinland. Passing this independent, third-party testing indicates that its solar modules — built upon four decades of continuous solar R&D — can perform with optimal output even in severe conditions including harsh marine, coastal, and agricultural environments.
