Abstract: The invention discloses a wireless underwater IOT (Internet of Things) system. The underwater IOT system comprises a deep-water sensor with fast underwater wireless communication built in a deep-water drone. The underwater sensor and drone are used as a node unit. The underwater IOT system is formed by the sensor with wireless communication built into an aquatic underwater vehicle. It is designed with blue LED with a receive and transfer data module. This is used as an information transfer component between both node units. The information is then relayed to a phone or website application.
