Automation of the farming system
Šimek, Martin ; Jirgl, Miroslav (referee) ; Arm, Jakub (advisor)
This thesis deals with the issue of the Internet of Things and its use in the automation of gardening areas. The processes that are necessary to maintain the operation of gardening facilities are both physically demanding and time consuming. The aim of this thesis will be to design a system that will reduce the need for human intervention in performing these processes. The main prerequisites of the proposed system include the modularity of the whole concept. The automation of the gardening areas focuses mainly on the irrigation system, which will be controlled by the designed wireless modules. These are STEM-01 modules which have the task of measuring soil volumetric water content, soil electrical conductivity, soil temperature and ambient temperature and relative humidity in the area, BVM-01 modules which provide irrigation in the required area and last but not least FDM-01 modules with which it will be possible to enrich the water located in the drip pipe and used to irrigate the mentioned areas with mineral fertilizers.

Network End Node for Spacial Monitoring of Atmosphere Parameters
Mlynář, Zdeněk ; Smetana, Lukáš (referee) ; Novák, Marek (advisor)
LoRaWAN end node is often a device composed of a sensor, or actor. In this case it is sensor monitoring atmosphere parameters. This can be used to investigate atmospheric impact on Free Space Optics. This work is firstly focused on physical layer LoRa, then on LoRaWAN communication protocol. LoRaWAN device classes are also described and examples of measurable parameters can be found at the end of the theoretical part as well. The practical part describes all components, which were chosen when designing this device, and lastly it comprises the schematic design. The result is printed circuit board design.

Well Water Level Measurement
Samek, Jakub ; Košař, Vlastimil (referee) ; Korček, Pavol (advisor)
This thesis deals with the well water level measurement. The main aim was to design and construct a device using proper platform and sensorics for measuring which is used for measuring the water level in the well. This device uses batteries. The expected battery life is several months. The device sends collected data via network to the server. These data are visualised in graphic interface using a graph. The system controls the water level in the well and battery level of the device. When the limit values are exceeded, the user is notified by e-mail. Based on this information, the user can decide how to be economical with the water.

Coexistence of wireless systems LoRa and Bluetooth
Paul, Filip ; Kratochvíl, Tomáš (referee) ; Polák, Ladislav (advisor)
Bakalářská práce je zaměřena na koexistenci LoRa a Bluetooth technologií v bezlicenčním 2.4 GHz ISM pásmu. Práce se skládá ze dvou hlavních částí, jmenovitě teoretické a experimentální. Ve své teoretické části se věnuje popisu fyzické vrstvy obou systémů a definuje koexistenční scénáře, které mohou mezi oběma systémy nastat. V experimentální části je navržen a zrealizován měřící testbed pro měření koexistenčních scénářů, které mohou nastat mezi LoRa a Bluetooth systémy v 2.4 GHz ISM pásmu včetně následného zpracování naměřených dat. Na závěr je navrhnuta laboratorní úloha a založená na experimentální části diplomové práce, která slouží pro edukativní účely pro kurz mobilních komunikací vyučovaný na univerzitě VUT.

Automated measuring system for irrigating plants with IoT connectivity
Lahoda, Vladimír ; Polák, Ladislav (referee) ; Kufa, Jan (advisor)
This bachelor thesis deals with IoT networks and considers their use as part of embedded devices. The purpose of this device is to control the flower bed or garden based by data from sensors monitoring the environment. The device not only controls the irrigation operation itself, but also sends all traffic data over the IoT LoRa network. Thus, the device also functions as a weather station, as all data are sent to a second device that acts as a receiver. This receiver displays the data and also sends them to the Internet, where the data are publicly available. The module for sending and measuring data is mounted on its own PCB and is covered in a waterproof cover, so they can be operated outdoors. There is an integrated battery, which is a backup of savings in case of power failure. The battery is designed to back up power for 25 days.

Wireless Communication Module for Educational Kit Minerva
Fiľo, Richard ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
In this thesis, we are concerned with the design of an extension module that will provide wireless communication capability to the Minerva platform. The result of our work is an adapter that is attached to the Minerva platform and then our expansion module is inserted into it using an M.2 connector. The module supports Wi-Fi 4.2, BLE 5 and LoRa standards. For the selected module, we have created a communication interface designed to work easily with the module. In the following, we present worked examples and a demo application using this module. All components are tested and work as we expect.

Wireless sensor based on LoRa technology
Pospíšil, Jan ; Krajsa, Ondřej (referee) ; Troják, David (advisor)
The bachelor thesis in theoretical part is focused on wireless technologies used for home control and automation devices where low power consumption is required. There are mentioned possibilities of each technology, energy requirements, range and throughput. The result of practical part is design and construction of a wireless temperature sensor which uses LoRa technology to communicate with a gateway and is also capable to last on battery for years. Additional feature is user possibility to use GPIO pins in form of relays. The task also covers design and construction of a gateway which listens for LoRa packets and communicates with PHP application on server side. Last step of practical part is focused on design of PHP application, which is responsible for visualization of received data.
