Position tracking using GPS coordinates
Mishustina, Ekaterina ; Podivínský, Jakub (referee) ; Sadovský, Petr (advisor)
This bachelor’s thesis is devoted to determining the location using GPS. The GPS module receives the GPS signal and forwards it to the development board, where it is subsequently stored in a data structure and forwarded to the server. The server processes data about the location of the device and reflects it on the map it generates. To gain access to view the data, the user must pass authorization and correctly enter the name and password. The theoretical part of the work is devoted to electronic data transmission, data transmission standards and protocols, GPS and also describes the basic properties and functions of the hardware used for the design and implementation of the device.

Home security system
Čada, Jan ; Burda, Karel (referee) ; Lattenberg, Ivo (advisor)
This master thesis deals with the design and implementation of a security system for a family house. It consists of a central control panel, a control keyboard and detectors connected using cables. The first part of the thesis discusses the electronic security and fire alarm systems, describing the individual elements of these systems and their different types. Magnetic contacts, fire detectors, sirens and a mains power supply with UPS function are selected from the current offer based on a comparison of parameters. In the next section, a block diagram of the whole system is designed. Raspberry Pi Pico development board with an RP2040 microcontroller is selected along with a GSM module SIM800L for SMS alarm notification and an Ethernet module with a Wiznet W5500 chip for the possibility of implementing a web interface. Schematics of the individual modules of the system are designed - for the central control panel, input module with PCF8574 circuit and two PCBs of the control keyboard module, which is equipped with a button keyboard with backlight, character LCD display type 1602 and proximity sensor VL53L0X for automatic lighting when person comes closer than a defined distance. PCBs are designed according to the schematics. Their manufacturing is then ordered, all components are mounted and the PCBs are placed in a 3D printed enclosure in the case of the control keyboard, and on the mounting plate of the metal cabinet in the case of the central control panel, according to the designed mounting plan. For the selected piezo sirens, covers are designed and 3D printed in the design of the selected Paradox NV5 motion sensors. In addition to the central control panel and the control keyboard, door and window contacts, fire detectors and sirens are installed in the house. The next part is dealing with the development of the control software for the central control panel and control keyboard in MicroPython language and the design of a custom communication protocol on the RS-485 bus for communication between the central control panel and control keyboard. Both control programs are based on the state machine principle, and their state diagrams are presented in the thesis. Part of the text is also focused on the development of the central control panel web interface and integration of the desinged system into the Home Assistant open-source automation system. The last part describes the activation and testing of the system in real conditions of a family house.

Weather station with air quality measurement
Lacina, Jaroslav ; Hájek, Jaroslav (referee) ; Lattenberg, Ivo (advisor)
This bachelor thesis deals with the design and implementation of the wireless weather station with air quality measurement. At the beginning of the theoretical part, meteorology will be analysed. Afterwards, this work describes physical principles and the method of measurement of physical quantities that are measured by the meteostation. Next is the folloving technology described - Internet of things. The weather station is powered by a single battery and operates autonomously without any user intervention. It measures temperature, humidity, atmospheric pressure, CO2 and tVOC. Measured data are saved in to the cloud service ThingSpeak using a GSM signal. Further the work focuses on creation of web applications. The well organized graphs are created from the measured values.

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.

Control of pump over GSM
Rybár, Vladimír ; Baštán, Ondřej (referee) ; Bradáč, Zdeněk (advisor)
The topic of the final thesis is the project and realization of the pump control using GSM. The present (actual, current) state of control unit of irrigation system is analyzed in the introduction of this thesis. The core of this thesis is to design new controlling irrigation system with using GSM control. In this thesis there are selected suitable (appropiate) components, which are meeting the assigment. After that, the control program was designed. The conclusion of the thesis is to verify the functionality of designed system, to summarize achieved the result and to summarize the possibilities of the system expansion options.
