Author: Táborský Zdeněk

Diplomové práce 2009

The subject of this diploma thesis is a design and a realization of device for information transmission under the water by using ultrasound. Concrete form allows sending text messages, user interface consists of a display and special keyboard, which use magnetic sensors. The aim of the work is a full design and manufacturing of functional prototype. It includes a choice of fundamental principle, assembling of communication chain, selection of all components, design of circuit diagram, making of layout for printed circuit boards and subsequent placement of components and testing functionality. The work is further aimed at implementation of basic software for microcontroller, creation theoretical concept of communication protocol and design of waterproof case.
