Control unit for aeroponic growing system
Vrabec, Miroslav ; Dulík, Tomáš (referee) ; Klozar, Lukáš (advisor)
This thesis deals with the history of a method of plants cultivation without original substrate. The method is hydroponics and its subsequent development is called aeroponics. This work outlines the design of the whole aeroponic system including a control unit. The control unit has been designed to control the injection of nutrient solution, which is essential to the life of plants.Further, the control unit performs the control of lighting period, temperature, air flow and also regulation of nutrient solution pH. The control unit also keeps records of all data necessary for the monitoring process and for the evaluation of time differencies in the system.

TZB Temperature control system
Březík, Petr ; Čejka, Miloslav (referee) ; Bejček, Ludvík (advisor)
This document deals with a measurement of house temperature, for air conditioning, controlled by micro. In the first part there is a whole system and design of future solution described. In the second part theoretical analysis of the most widely used methods of temperature measuring is elaborated. The following part handles the market research considering the solution in industry companies. In a list there are compared the most used sensors, which are used for temperature measuring mainly in AC. In the fourth part a chosen sensor is in detail described, along with its communication and inner functions. In the fifth part there is a micro controller Microchip PIC16F876A for measure board designed. Then a scheme of printed circuit is presented. In the last chapter a software solution of terminal and micro controller.

Wireles Flying Object Telemetry
Bednář, Martin ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
This paper is engaged in specification, design and implementation of a telemetry module for flying object. Specifically, it focuses on the selection of the appropriate carrier frequency of the integrated circuit providing bidirectional communication to a sufficient distance and design of the protocol used in the transmission. Furthermore, the document focuses on the design of communication modules using these integrated circuits, altimeter sensor module, module to control the actuators and design of the application for mobile phones used to display the measured data. With regard to legislative and technical options, I chose a carrier frequency of 2.4 GHz. For this frequency is commercially available integrated circuit CC2511, which in cooperation with integrated circuit CC2591 should be able to provide telemetry range about 2 km. I chose BMP085 sensor for altitude measuring. It is communicating over I2C bus as well as a module for controlling the actuator, which uses a microcontroller ATMEGA48-20AU. The mobile phone communicates with the ground station via the USB bus.

Implementation of drivers for wireless sensor unit
František, Milan ; Šimek, Milan (referee) ; Botta, Miroslav (advisor)
This work is concerned with the use of digital and analog sensors with wireless unit IRIS. There is a basic description of the software stack BitCloud, including important functions with a used sensor types and used buses. In the work is described procedure for creating drivers for the various sensors and their implementation in a stack BitCloud. In conclusion of this work is a practical example of right implementing of the individual drivers.

Laboratory tool for teaching and demonstrating buses
Mutina, Petr ; Pristach, Marián (referee) ; Levek, Vladimír (advisor)
The goal of this bachelor thesis is laboratory tool design and realization, which is suitable for teaching and demonstrations simple buses (UART, RS-485, I2C, SPI, 1-Wire, CAN, current loop and IR transmission). Despite the fact there are many possibilities of signal transmission, this thesis deals with metallic buses only. The only exception is infrared light data transmission, that was added as an example of optical wireless communication. First, basic terms are defined and used technologies are described, then circuit design is made, finally, laboratory tool is made and tested.

System for Household Monitoring and Automation of Central Heating
Svoboda, Tomáš ; Nevoral, Jan (referee) ; Šimek, Václav (advisor)
In this work, which belongs to the field of embedded systems, several hardware modules and central control unit for home automation purposes were designed and subsequently implemented using 1-Wire bus and tiny computer Raspberry Pi. Furthermore, an extensive application for management of automation activities in a given system was created in C++ programming language. This piece of software is running continuously as a service from computer boot time until its shut down. There were implemented several functionalities that enable controlling the general purpose relay to switch home appliances and to operate central heating automation features, which include operating of electronic actuators on the radiator and boiler. In addition, web-based application allows direct monitoring of automation activities and provides necessary means to plan the desired actions of the available units within the automation system. Resulting system could be installed on a target site and monitor temperature, automate central heating and switch basic home appliances using relay. Main advantage of the created system can be recognized in scalability where new automation tasks or devices could be added.

Management and Automation of Enterprise Facility Heating System
Hartmann, Jiří ; Bardonek, Petr (referee) ; Šimek, Václav (advisor)
The aim of this work is to create a unified control and supervision system, SCADA, for controlling the heating and cooling of the company. The system is controlled by UniPi PLC units. Node-RED is used as control software. The user interface is created by an extension "dashboard". For communication between elements using the MQTT protocol. The InfluxDB database is used for data storage. The Grafana tool is used to visualize historical data. The majority of the created system consists of open software. The system is universal, expandable and it is possible to connect it with another system. The system can be used or adapted to similar problems of advanced heating control.
