Temperature monitoring unit
Martínek, Jaroslav ; Kovář, Jan (referee) ; Kolka, Zdeněk (advisor)
Content of the Bachelor Thesis covers design and realisation of an unit for multipoint temperature measuring in cooling and freezing equipments in food stores and shops. As a controlling microcomputer is used an Atmel ATMega128, temperature sensors are realised by DS18S20 digital thermometers, connected via 1-wire bus. Unit can read temperature from 32 temperature sensors, includes memory for measured data, real time clock, Ethernet interface and display with buttons for basic user control. Temperatures are measured periodically with user defined interval, values are stored into internal memory and showed on display. Measured data can also be transferred via Ethernet to clinent PC, where can be viewed in form of table and graphs.

Two sensor temperature measurement
Novák, Lukáš ; Háze, Jiří (referee) ; Pavlík, Michal (advisor)
This thesis deals with PCB design and programming of microcontroller AVR, that communicates with WiFi module and Dallas brand thermometers. Wifi module sends data to internet database. In case of communication malfunction informations are saved into microcontroler´s EEPROM. When communication is restored informations are send to database.

Solar pool heater
Jablončík, Lukáš ; Chladil, Ladislav (referee) ; Šteffan, Pavel (advisor)
The master´s thesis deals with the design of the solar heating regulator of the swimming pool. The basis was to study the available solutions for the solar pool controllers, to define the requirements, to design the concept and the block diagram of the own thermostat. The thesis also provides a description of several for the Internet of Things. The most suitable is used to control the thermostat. The resulting thermostat regulates two power outputs for filtration and the pump, it can be set using the keyboard and graphic display. At the end of the work is practically verified functionality on the model and on the real pool with solar heating.

Control System for Mobile Platform
Sárközy, Imrich ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
The aim of this work is to design a control system for a mobile platform with an AVR microcontroller. It’s function is to control two DC motors, one stepper motor and read information from sensors. At first, our work is to develop an electrical scheme and circuit boards for the control system. Debug the microcontroller’s program for correct handling of the peripherals. The next step is to connect sensors for non electric quantity and modify the microcontroller’s program to handle them and send received data from them via bluetooth connection.

Remote-controlled cross-country four-wheeler
Kejzlar, Radim ; Novák, Lukáš (referee) ; Háze, Jiří (advisor)
The bachelor's thesis focuses on the complete design and implementation of an RC vehicle controlled by a smart device with the OS Android using Bluetooth communication. The RC four-wheeler is designed in accordance with the requirements of the BUT FEKT interactive gaming room, where this vehicle is intended. The work deals with the electrical, the program and mechanical part. The electrical part includes a complete selection and description of the drive, implemented using a BLDC motor and its controller. The controller is controlled by a control unit in the form of a microcontroller from the AVR family, which also processes the received data from Bluetooth communication. The design also includes a suitable selection of the Li-Pol technology battery and its capacity. The program part deals with the development of an application for the Android OS using the Mit App Inventor 2 development platform, and in the mechanical part the chassis used for the RC four-wheeler and the design solution of the entire design are discussed.

Auxiliary winding supplying the voltage regulator of synchronous generator
Hrtáň, Michal ; Hájek, Vítězslav (referee) ; Vítek, Ondřej (advisor)
The theme of this thesis is the design and verification of the auxiliary winding to supply the voltage regulator of the synchronous generator. The synchronous generator for which the auxiliary winding proposed is three-phase, low voltage with double layer random wound stator winding. The generator excitation is brushless with auxiliary rotating exciter. The auxiliary winding is designed for placement in the stator teeth, along with the main winding. The sizing of the auxiliary winding is derived from the power requirements the voltage regulator. Draft winding is validated analytical calculation and finite element method (FEM). The auxiliary winding has been implemented in the production of the generator. The Features of the auxiliary winding have been verified by measuring the by electrical testing room and the test results are evaluated.

Environment control with microcontroller
Králíček, Martin ; Šebesta, Jiří (referee) ; Fedra, Zbyněk (advisor)
This bachelor project focuses on equipment for environment management and check with help of microcontroller. This equipment should enable us to check and manage home environment for example for goldfish, hamsters, spiders and other small pets. Further on, this project describes individual parts of equipment which the ECM-01 consists of. ECM-01 is consists of general block, feed block, relay block with power supply and sensors. The ECM-01 consists of several functional blocks which are controlled by the main microcontroller. The functional blocks contain measurement transducers and action units. The choice of blocks depends both on individual environment and the user. The user can choose which values he needs to control and measure.
