The diploma thesis is about designing device which monitors temperature and humidity. In the first part of thesis are explained basic terms, importance of key variables and on market offered products are described. After that the thesis describes device concept design with schematic designs. From designed schematics are described printed circuit board designs. Next part is about device commissioning and correction of errors caused by incorrect design. Last part is about program designing and device testing.

The goal of diploma thesis is design of programmable control system. This system can be used for regulation of basic parameters in an aquarium. Primary parameters for selection of this device are the price and the easy realization of final device. In first step there are selected parameters, which are needed to control. In second step there is described which kind of sensors can be used for measuring of selected parameters and suitable regulation of necessary parameters. The device is supposed to communicate with PC by USB and this communication is going to be compatible with an old RS-232. Device must be completed with hardware design. Device will be in principle system with real time, that is the reason why device will contain microcomputer. A microcomputer must communicate with other integrated circuit in the device and it supposes to communicate with PC. In specific chapter it will be described, how many different kinds of communication it is possible. For microcontroller it is necessary to create a program, which can figure the measured parameters and it also allows setting up the way how parameters can be regulated. Measured parameters are supposed to storage in the specific memory for the later interpretation. The completely device must be put into a case, which is calculating with a damp place. There must be created a host application for PC. This application suppose to detect if device is connected, figure measured parameters and also allows to set up the way, how to regulate the parameters and display the storages parameters. The application is suppose to run on the operation system created by Microsoft (Windows XP and Windows Vista or later). Diploma thesis contains a problem of the analysis which parameters may be controlled and the way how it can be controlled. There will be selected the sensors, which are suppose to measure and there will be described the basic data transfer and the specifications. It will also contain description of the hardware and software implementation of the device and possibilities of the user’s settings. There will be described the host application and its possibilities. Finally there will be described a functionality of the device and the host application. It will be also imagined some system upgrades for future.

Altimeter measures atmospheric air pressure and counts actual model altitude from it. Then sends data to ground module, which shows them on display. Ground module contains USB interface for connecting to PC. It enables upload of flight data and opportunity to show them in graphical representation.

This diploma thesis deals with covers design and realisation of device for multipoint temperature measuring in fotovoltaic systems. As a controlling microcomputer is used Atmel ATMega128L, temperature sensors are realised by DS18S20 digital thermometers, connected via 1-wire bus. System can read temperature from x temperature sensors, includes memory for measured data, real time clock and display with buttons for basic user control. Temperatures are measured periodically, values are stored into internal memory and showed on display.Measured data can also be transferred via seriál bus to clinent PC. Device is projected as a battery-operated compact tool. The final realization is made with respect to minimal system requirements and to possible future extensibility for wider usage spectrum.

This thesis deals with the issues 6LoWPAN protokolu and implementation of IPv6 on the specied platform. Introduction thesis deals with the explanation of wireless sensor networks. Next it was descibed 6LoWPAN protocol, which maps IPv6 on standard IEEE 802.15.4. The thesis further concentrates to exploration of possible operation systems, that are designed for sensor networks and then followed by comparison of their characteristics and advantages. The fth chapter is focused on he implementation of the operating system to the sensor node Iris, introduction Iris and with the structure of the operating system Contiki OS. At the end of thesis is description of the implementation of this system in the sensor node Iris.

The thesis deals with the design and implementation of smart house lighting. In the living parts of the house, the light intensity is maintained at a constant level which is set by the user. The intensity of lighting can be set manually for each room from a central module with a user interface. It can also be changed by any remote control directly in the room in which the user is currently located. When the remote control is used, the information about the change of light intensity is transmitted to the central module. For communication between the central module and the luminaires, the existing power lines are used.

The aim of this thesis is to design and implement an industrial programmer AVR microcontrollers from Atmel. The first section provides the theoretical knowledge of the AVR microcontroller. Furthermore, comparison of methods for programming the microcontroller and the selected method is an analysis of the speed of programming. The following is the entire design of industrial programmer which is implemented in the programming environment Eagle. In the penultimate part of the proposal is designed PCB. The final section is devoted to the revival of the programmer and programming.

The target of this work is to modernize air-conditioning control of the unit Thermal Chamber. The old air-conditioning unit will be renewed by replacing old one by new one, microcontroller-driven control unit, trough which it will be possible to show the current and desired temperature LCD. Theoretically description of the components and methods of measuring the temperature and environment for the creation of the microcontroller is shown before construction.

This master's thesis deals with design of simple embedded system based on Atmel ARM. There are Atmel's products covering this market segment reviewed in the first part, including the description of a couple of devices. The second part is focused on the aim specification, selection of components, their interconnection, power-supply requirements, price considerations and the design itself. The next chapter describes testing and application of the platform. The conclusion presents the current state of the project and deals with the successive progress.

The goal of this project is explore and study the ways of metal detecting and create a metal detector for industrial use. When the device were inventing, a lot of methods were studied and the impulse detect method were chosen as the most perspective way of metal detecting, thanks to a huge electronics parts possibilities. After experiences with preceding device was necessary to redesign it. Main target of this thesis is to increase the computing power of detector. For this purpose will device need a new microcontroller. Device will communicate with PC trough a USB port. The device will have a battery which allows device to run for a few hours. Processing of measured data will be make even with DFT which will lead to better analyze of mass and type of conductor under device.
