Sensor fusion complex underwater navigation device for scuba divers

摘要

The present invention relates to a sensor converged underwater navigation (1000) for a scuba diver, comprising: a lower case (100) respectively having a lower induction hole (110) at the bottom side, and a lower accommodation groove (120) for accommodating a smartphone at the top side, and having a lower transparent window for filming (130) at a part which is oriented to a camera of the smartphone in the lower accommodation groove (120); a PCB (200) installed with a pressure sensor (210) which seals the lower induction hole (110) and which measures the pressure of a fluid induced to the lower induction hole (110), a water temperature sensor for measuring the temperature of the fluid, an interface for providing a USB/Serial communications with the pressure sensor and water temperature sensor, and an MCU for controlling the pressure sensor, water temperature sensor, and interface; a cable (300) for connecting the interface with smartphone; an upper case (400) of which rim of the bottom side is attached to a topside rim of the lower case (100), and which is formed with a transparent window for observing liquid at the top (410) at the top side; and an auxiliary button (500) which vertically penetrates the transparent window for observing liquid at the top (410), and of which bottom end presses a predetermined part of the smartphone when the top end is pressed. According to the present invention, a water pressure measured underwater is displayed on the screen of a smartphone, and a user can check on the surrounding water pressure underwater in real time basis.
