Water alarm devices, systems and related methods

摘要

A water alarm device for releaseable attachment to a user in a body of water includes a buoyant alarm unit having a water sensor. The water sensor is configured to sense if a sensing portion of the alarm unit is in contact with water. A timer is in communication with the water sensor and is configured to determine a duration of water contact with the sensing portion of the alarm unit. The alarm unit is configured to travel to a surface of the body of water and activate an alarm when the duration of water contact is greater than a predetermined time.
