Control system for greenhouse
Haring, Filip ; Jirgl, Miroslav (referee) ; Bradáč, Zdeněk (advisor)
This project deals with design and implementation of control system, which is used for regulation climate conditions in special grow box. Measured values are displayed on graphic LCD, sent to application in PC or displayed on web server. The project solves software and hardware implementation of measurement system.

High-intensity strobe light source
Rehák, Ondrej ; Drexler, Petr (referee) ; Szabó, Zoltán (advisor)
This bachelor’s thesis discusses influence of high-intensity light strobes on human. Content of this thesis contain description of human sight and reaction of human sight to high-intense light strobes and consequently using this information to create device for temporal disable or disorientate of attacker. High-intensity light strobe source was designed to be light-weighted and compact. The case was designed and made on 3D printer, device is powered by lithium-polymer battery.

Power LED Current Analyzer
Ryba, Ivan ; Vochyán,, Josef (referee) ; Šebesta, Jiří (advisor)
This thesis describes attributes of LED, especially high power LED. Evaluates posibilities of measuring the current passing through the high power LED device in the automotive industry. The basic requirement for the analyzer is adjusting it for the voltage and current through LEDs. Analyzer have to display the mean current and frequency. Additionally also minimum and maximum current, duty cycle and amplitude might me displayed. The central element of the device is ATmega16 microcontroller.

LED light with adjustable spectral radiation for breeding and growing
Satora, Ondřej ; Hrach, Petr (referee) ; Klozar, Lukáš (advisor)
The aim of my master’s thesis is the design of the LED lighting system for breeding and growing purposes as replacement for the classical high-pressure sodium lamps and other sources of light used today. The whole system can be controlled locally by buttons or remotely by web server using Ethernet interface. LEDs are powered by five-channel step-down converter with current feedback. Converters are controlled by pulse width modulation generated by microcontroller.
