By definition, the Internet of Things (IoT) should connect with anything -- even writhing, kinda gross, but often delicious eels. SK Telecom's latest project is aimed at showcasing its IoT skills with a pilot connected eel farm that uses a network of sensors to monitor thousands of eels, mostly autonomously. Sensors dotted across multiple 20-foot-wide tanks check on water temperature, pH and oxygen levels, Data is then collated and analyzed by the Korean carrier's cloud system, and bounced to a simplified smartphone app -- all in pretty much real time. "Why?" is a good question, but there's a good answer too: apparently minute changes in those factors above can be fatal to young eels. Before, this meant regular tank checks by workers every two-to-six hours. Now, it's mostly automated and sudden changes will even ping a warning to eel farmers' smartphones when needed. SK Telecom is planning to roll out the system commercially next year -- who knew eel farming was big business?
