Security system
Papoušek, Marek ; Bohrn, Marek (referee) ; Pavlík, Michal (advisor)
The work deals witch design and realization of create an electronic security device based on Atmel AVR microcontroller’s family. Individual elements of security, together they communicate using XBee wireless interface. The device should provide notice through the GSM network disruption when guarded zone. Communication between the microcontroller, GSM module, and XBee module will be provided via USART bus. The whole system should take account of energy savings when using battery power.

Communication between the Android OS and Arduino Platform
Mychko, Maksim ; Rozman, Jaroslav (referee) ; Samek, Jan (advisor)
This thesis deals with creating a library for the Android OS which enables efficient wireless communication with platform Arduino. The target is to create an application for Android OS, using a created library that allows you to capture data from various sensors and control effectors. The work describes basic wireless interfaces for Android OS and Arduino platform. The main benefits and drawbacks functions are also introduced. The comparison of current consumption for modules HM-10 and DIGI S1 has been carried out as well. Possibility of data acquisition and effector controlling exercises have been tested and verified.

Wireless sensor for indoor monitoring
Partika, Marek ; Jirgl, Miroslav (referee) ; Hynčica, Ondřej (advisor)
The work deal with programming interface for sensors and wireless transmission of the data. Communication with the sensor is solved by SPI and I2C protocol. For programming interface is used object-oriented programming techniques language C++. The wireless transmission of data is used XBee RF module. Here is proposed solution the correct format of data ready for send and method itself sending data. Data are received and displayed in the final application in the PC that is also able to send the selected data to the web, where data are displayed online.

IEEE802.15.4 and ZigBee technologies, examples of applications
Skládaný, Vojtěch ; Frýza, Tomáš (referee) ; Kováč, Michal (advisor)
The main goals of diploma thesis are application and realization of tool for projection and installation wireless networks according to IEEE802.15.4. The thesis is specialized in construction of transmitter and receiver device in term of mobility and visualization of data measured in terrain. Than the software support for measuring and control appropriate periphery are summarised and described. The system is defined in C programming language and uses OpenMAC library. Last part of thesis is focus on practical measurement and testing tool for projection and installation wireless network.

Device for sports results measuring and displaying
Frelich, Marek ; Zelinka, Petr (referee) ; Frýza, Tomáš (advisor)
This project is dealing with a design of device for measuring and displaying of sports results. The project is divided into three parts - the design of control board for LED display, next the control unit and finally the remote control. LED display contains LED segments and graphical line for the text. The control unit and remote control are communicating with LED display, measuring devices or with a PC. It is possible to operate the whole system by tablet or a smartphone. There is a software made for all processors of all parts, which can demonstrate the function of the system and all added peripherals.

Robotic Rover Controlled with Using the Arduino Platform
Čechmánek, Martin ; Luža, Radim (referee) ; Samek, Jan (advisor)
The goal of this bachelor's thesis is to introduce options of wireless robots control with using Arduino platform and describe preferences, options and use of this platform. In this thesis is implemented duplex wireless transfer between modules with XBee modules. Practical part of thesis consists of 2 parts - control module and robotic rover module. Control module is used for controling the other module and it contains display, signal and control parts. Rover module, which is based on SRV-1 robot, contains ultrasonic sensors for distance measuring between rover and barrier around its place, and LED light ramp for lighting places out of the current direction of movement.

Low-power wireless sensor node
Pobiecky, Michal ; Koton, Jaroslav (referee) ; Krajsa, Ondřej (advisor)
The main purpose od this thesis is to design wireless sensor node with emphasis on low power consumption. This device is firstly made of microcontroller Atmel ATmega328P and for transferring measured data XBee 802.15.4 or transceiver nRF24L01 is used. Subsequently there is a design with Atmel ATmega256RFR2 with integrated wireless part and Lightweight Mesh protocol. Special attention is given to sleep modes and lowering power consumption. For ATmega328P the measurement of these power modes is done.
