Wireless Sensory Network Using LoRa Technology
Mikulášek, Michal ; Pokorný, Jiří (referee) ; Škorpil, Vladislav (advisor)
The bachelor thesis focuses in the first half on the Internet of Things and the available wireless technologies for the Internet of Things. Each technology is characterized by its features, pros and cons, as well as the possibilities of using it in the Internet of Things. In the second half of the thesis, a practical design and construction of a LoRa network, consisting of a sensory and a central unit, is carried out. The parts of the solution are designed wiring schemes, printed circuit boards and detailed photo documentation. Additionaly the software solutions for both types of units are described, with detailed descriptions of the proposed features. The maximum possible range is tested and documented for the entire solution. Subsequently, a detailed measurement of the power consumption of the sensor unit is carried out and an extensive estimation of its battery life for a selected battery.

Datalogger or building constructions
Hendl, Adam ; Streit, Jakub (referee) ; Bradáč, Zdeněk (advisor)
The bachelor thesis deals with automated measurement of temperature, humidity and pressure in building structures. In the section dedicated to my work is primarily a process as I progressed in implementing the task. The next section describes the parameters of the components used to implement the measurement and data storage. This work also includes a design of a printed circuit board that includes auxiliary and measuring circuits.

Wireless IR Sensor for Area Invasion Detection
Suchý, Lukáš ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
The target of this Bachelor thesis to design a security system for detection of the monitored space disruption, containing several battery powered sensors which are connected to central unit. From Bachelor thesis is evident, that for communication is to be used integrated circuit SI4432. Sensor detects motion in distance no less than 5 m and sends reports of the space disruption to central unit where this information will be processed. After that the user will be informed by the central unit. Sensor unit should be battery powered with lifetime in years. In conlusion, the system it tested in real work.

Low-power wireless sensor node with ATMEGA328
Klvaňa, Jakub ; Pál, Tamás (referee) ; Krajsa, Ondřej (advisor)
The aim of this semestral thesis is to design low-power wireless sensor node, which will be used to measure temperature, humidity and pressure. The first part deals with the central unit, which will collect and process the measured data. The second part is devoted to design for a wireless node that is formed by ATMega328 microcontroller, three sensors (temperature, pressure and humidity), baterry which is charged by photovoltaic cell and the wireless module. Conclusion is a brief summary of this work and outlines follow-up procedure in dealing with the bachelor’s thesis.

Datalogger
Štupák, Branislav ; Bejček, Ludvík (referee) ; Beneš, Petr (advisor)
The bachelor thesis deals with the datalogger development for monitoring roof constructions ambients of historical buildings. The device is made of microcontroller ATmega328P and is using simple principles of environment monitoring. The device saves measured data to SD card from air temperature, air humidity, light intensity, wood moisture and air flow sensors. In conclusion of the thesis are then succesfully tested and summarized the properties of designed datalogger’s sensors.

Control system for cantilever gates
Koždoň, Ondřej ; Arm, Jakub (referee) ; Bradáč, Zdeněk (advisor)
The goal of this bachelor's thesis is to design a battery powered control system for wireless controlling swing gate (may be used for cantilever sliding gates or garage doors). This system is designed as a small electronic system with necessary Inputs/Outputs (I/O) and an Input for charging a battery from solar cells. The result of this bachelor's thesis are two main PCBs with dimensions of 5×5cm for controlling the gate and remote controller with dimensions of 2,3×4,4cm. Main PCB allows adding more remotes, deleting all remotes and modes for the way of controlling the gate (opposite direction, open only, close only, open wing, close wing, stop the gate) and selecting Master/Slave gate. Communication works on frequency of 434MHz.
