Design of Sensor Modules for ZigBee Wireless Network
Tichý, Andrej ; Vašíček, Zdeněk (referee) ; Šimek, Václav (advisor)
The purpose of this study is to contribute to spreading of the global phenomenon IoT and to create a sensory network. In my study I focused on the development of active and passive modules using the IEEE802.15.4 standard based on the ZigBee protocol. When creating my modules I was using the micro-controller CC2530 by Texas Instruments having the processor platform 8051. To implement the communication firmware for sensory modules I used the Z-Stack 3.0 implementation. The main communicator uses the CC2530 micro-controller as ZigBee network preprocessor and miniPC raspberry pi as ZigBee application processor. As a part of this study I created an active module that enables to control the relay; an RGB led strap using the PWM modulation and also the electric current measurement using noninvasive sensors. I also created a passive module including sensors BME280, TSL2561 and DHT11 to measure the air pressure, temperature, humidity and light intensity. Furthermore I created an universal module that makes easier the creation of new prototypes. Not least I created all-purpose raspberry mini-module. The relevance of this study is given by creation of module prototypes using the ZigBee protocol. Special value within this study has the the mini-module for Raspberry Pi which can be used in various roles within the ZigBee topology.

A Gateway for Xiaomi Aqara Devices
Urbánek, Petr ; Koutenský, Michal (referee) ; Pluskal, Jan (advisor)
This paper deals with creating gateway for smart devices of brand Aqara. There is discussed ecosystem of Aqara devices, which are used for testing and reverse-engineering of communication. The Gateway is implemented on platform ESP32, which is using cc2530 system-on-chip. Newly made gateway makes a bridge between ZigBee and MQTT protocol, which provides connectivity betweeen sensors and actors from Aqara and Home Assistant. Thanks to the Home Assistant are all data about home safe and creating new home automatizations is a lot easier.
