<p>Disclosed is a buoy sensor including a loss prevention device. The loss prevention device is capable of confirming the location of the buoy sensor and preventing the loss of the buoy sensor by a loss prevention means. The loss prevention means floats on the water, even though the buoy sensor sinks under water after running out of electricity. The buoy sensor comprises: a sensor unit including a power supply unit; a fixation unit surrounding a part of the sensor unit; a buoyancy weight surrounding a part of the sensor unit, and capable of being combined and separated from the fixation unit; and a loss prevention device install on one surface of the fixation unit. The sensor unit additionally includes a control unit issuing a command for the buoyancy weight to be separated from the fixation unit, in case the remaining current amount of a power source is under a predetermined value. The loss prevention device includes: a case installed on one surface of the fixation unit to be parallel to the sensor unit and having an open upper space; and a ball mounted on the open upper part of the case and floating on the water when the sensor unit sinks under water.</p> |
