Economical LoRaWAN security device
Varhola, Oliver ; Zeman, Václav (referee) ; Škorpil, Vladislav (advisor)
This master thesis contains a proposal of the solution for economical and energy saving security device with its communications part in a LoRaWAN network. Theoretical part of the thesis describes the most widespread LPWAN networks, i.e. the networks for low-power devices, such as NB-IOT based on LTE technology, Sigfox and LoRaWAN. Also briefly analyses security threats in case of the interference exploitation of the communication channel and describes LoRaWan security in detail. In the practical part there is hardware, power, mechanical solution implemented including the cover of the device. Realization of the software part covers, which types of events should be operated, power saving methods and mesage sending inverval are described. All requirements were implemented at application layer utilizing - LoRaWAN network server and virtual machine applications: MQTT broker, NoreRED, OpenHAB and cloud database InfluxDB with visualisation of the data in Grafana application.

Wireless Localization Module with Low-Power Firmware Based on RTOS
Lipka, Radim ; Bardonek, Petr (referee) ; Šimek, Václav (advisor)
This thesis focuses on the design and implementation of the wireless localization module, using UWB technology with emphases on low-power firmwre based on RTOS. Wireless localization is based on TDoA algorithm. The resulting HW module is designed as a four layer PCB, based on MCU crf52832 (ARM Cortex M4) and UWB module DevaWave DW1000. Firmware is implemented using FreeRTOS with emphasis on low power consumption. For hardware implementation, Eagle CAD was used. Firmware is implemented in C and Assembly programming languages.

Development localization board
Szabó, Michal ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
This document describes a device capable to determine geographical position thanks to its GNSS module and measure the change of movement with the help of an accelerometer and gyroscope. Outputs of these integrated circuits are combined, data are processed and fused thanks to a numerical integration and mathematical filters. Results are stored on a memory card. The whole development is described from a concept, through the making of the device and software algorithms to the testing of its functions.

Field sensor network for microclimatological measurements
Juráň, Radovan ; Frýza, Tomáš (referee) ; Povalač, Aleš (advisor)
Tato práce je zaměřena na návrh terénní bezdrátové senzorové sítě pro mikroklimatologická měření, zejména výronů juvenilního oxidu uhličitho v oblasti hydrotermílního krasu, založené na LoRaWAN. V teoretické části práce je předložen přehled cílové oblasti, možností řešení měření, získávání a přenosu dat. Praktická část se pak věnuje kompletnímu návrhu celého systému, to znamená od měřicího zařízení přes koncentrátor a gateway až po backend odesílání dat do cloudového úložiště. Výsledky tohoto komplexního problému jsou prezentovány průběžně a přílohy obsahují detailnější a názornější ukázky.

Power monitoring of IoT devices
Verčimák, Mário ; Jirgl, Miroslav (referee) ; Bradáč, Zdeněk (advisor)
This thesis describes energy consumption and power supplying low-power IoT devices. There is general analysis of current consumption and selecting suitable primary battery cell depends of behavior battery type. The next point is analysis of low-power and high-effectivity DC/DC convertor’s feature. The second part contains available solutions for energy monitoring and current measurement. This thesis also contains design of device for measure these energy consumption, with user application, which interprets measured data.

Smart Wearable
Moravec, Luboš ; Macháň, Ladislav (referee) ; Šteffan, Pavel (advisor)
This master’s thesis deals with the explanation of the concept of smart wearables and the different application possibilities. This work also includes examples of finished demonstration devices in this category. Part of this work is devoted to guide the selection of appropriate components for the design of new equipment in the category of smart wearable. The result of this thesis is designed wearable and charging station. This device is able to read user input and display that information on a smart device running under Android system connected via Bluetooth technology.
