Temperature and humidity monitoring devices with wirelless communication
Hrbáček, Zdeněk ; Arm, Jakub (referee) ; Bradáč, Zdeněk (advisor)
The purpose of this work is to design and implement a device for collecting temperature and humidity from bee hive. The system consists of a measuring unit that contains digital sensors and actuators.The system transmits the measured values wirelessly to the parent unit, which displays the data in a suitable format to the user. The user can monitor the hive parameters and use the actuators to adjust the temperature inside the hive. The whole system then operates autonomously according to defined rules.

Universal Sensoric Platform with Programmable Features
Gál, David ; Nevoral, Jan (referee) ; Šimek, Václav (advisor)
The aim of this thesis is to design universal sensoric platform for data collection in manufacturing environment. Device is capable of collecting data from variety of sensors, but it is also able to control external systems. Platform is controled by Lua scripts. The scripts are generated in user friendly visual programming environment Blockly. Platform is based on WiFi module ESP-WROOM-02.

Analysis of wireless network traffic
Guznar, Martin ; Kubánková, Anna (referee) ; Novotný, Bohumil (advisor)
This work solves the VoIP call switching system android with standard Long Term Evolution (LTE) on the IEEE 802.11 standard without losing the connection. In the theoretical part they are described in detail the various standards, protocols, their description and their interconnection. The proposed test will be in the system android with ongoing VoIP call. The outcome should be a capital loss graph Wi-Fi signal and follow your phone’s connection to LTE through a local provider, and all this without losing the connection and interruption of that ongoing VoIP call. The results of this study make it possible to determine how and under what circumstances will switch network from Wi-Fi to LTE and how it happened. Furthermore also obtain data that take place between a precise description of the procedure soft handoff.
