Ultra sonic SCUBA diver tracking device hardware

Abstract

Currently, there is no accurate, low-cost method to track divers. Watching bubbles can give you an approximate xy-location, and expensive underwater radios utilizing ultrasonic waves can work if the diver knows where they are. Traditional radio waves do not work well in water due to the conductive nature of water. The prototype made in the project uses an active sonar system that triangulates a single remote device’s position and displays that position on a computer. The design is not waterproof, but does accurately plot the position of a remote device in air. The documentation contained in this thesis describes the design process the author experienced, the technical behavior of the final product, and the use of the product.
