Meassuring system for building constructions
Vladař, Martin ; Franek, Lešek (referee) ; Bradáč, Zdeněk (advisor)
This thesis deals with the measurement of physical quantities in building using decentralized system for data collecting. The system consists of Raspberry Pi as a master device of the system. There are three branches connected to this master device. Each branch consists of up to 32 modules for data-concentration from sensors of physical quantities. The Raspberry Pi has implemented web interface for displaying measured values and system administration.

Digital secondary clock
Hortvík, Martin ; Mašek, Petr (referee) ; Marada, Tomáš (advisor)
The aim of this thesis is to design and implement control electronics for digital secondary clocks. The first part is focused on familiarization with the issue of the use of secondary clocks. Subsequently, the work deals with the design of electronics for generating minute pulses. The first part of the proposal is to ensure the correct voltage size and polarity of pulse. The exact timing pulses are provided by a pair of control circuits, Atmega8 microcontroller and RTC. The last part describes the procedure of realization of electronics by making schema, design and manufacture PCB, circuit revive and the implementation of the module into case.

Temperature Measurement with Microcontroller Aid
Harčár, František ; Holý, Miroslav (referee) ; Zuth, Daniel (advisor)
The thesis focuses on possibilities how to use inexpensive microcontrollers for temperature measurement. The designed module is appropriate both for laboratory curriculum, as well as for application in automation industry. A brief introduction is followed by a general explanation of the notion „measurement“ and a measurement history overview. Afterwards, there is a focus on history and development of temperature measurement and types of applied sensors. Conseguently, there is the thesis itself , its description, principles, connection schneme and measurement methodology. Finally, the thesis regards its commitment and findings.

Laboratory model of an machine for printed wiring
Posekaný, Jan ; Kaczmarczyk, Václav (referee) ; Zezulka, František (advisor)
Production of printed circuit boards using three-axis CNC milling machine is suitable for small batch production. Milling machine consists of three axes, which are controlled by stepper motors. Controlled by a PC connected to the control electronics to communicate over the serial line. Input data is exported from the Eagle design software. The core of the control unit´s processor family, the AVR ATmega16, motor drivers for the ATmega8. Transfer between PC and the device is implemented using a virtual person through USB.

HVAC unit for optical head
Janošík, Tomáš ; Šotner, Roman (referee) ; Kincl, Zdeněk (advisor)
This thesis deals with the design of a HVAC unit for temperature regulation inside an optical head. The unit is completed by functions which optimize its reliability such as checking of fan, heating element, monitoring a supply voltage and saving operating information into the memory. The device communicates with PC via serial interface RS-485. There is also described the possibility to switch the unit to a manual mode, in which the temperature interval is setting by a potentiometers. Solution of this thesis is function prototype.
