Experimental Platform for Free-Space Optical Communication in Water
Kousal, Martin ; Fedra, Zbyněk (referee) ; Král, Jan (advisor)
For the needs of underwater drones and seabed exploration, a live image from a camera mounted on the drone needs to be transmitted to the operator. Therefore, a hardware platform has been developed to research and experimentally verify the possibilities of cable-free optical communication in an aquatic environment. In this paper, the possibilities of communications in aquatic environments and their limitations are discussed. Furthermore, a communication chain of transmitter and receiver is designed and then simulated in Python. This proposed communication chain is then implemented. The FPGA configuration of the transmitter and receiver is described, and handlers and scripts are created to receive and process the transmitted signal. Finally, real measurements are performed in air and also mainly in a water environment, where the functionality of the whole chain is verified. In the last part of the paper, possible improvements and their impact on the whole platform are outlined.

IoT air monitoring
Kousal, Martin ; Povalač, Aleš (referee) ; Frýza, Tomáš (advisor)
The purpose of this bachelor work is to make a device that can measure air quality parameters and send them wirelessly to the server, where that measured data are processed and then shown to the user. The aim is to create a device with the lowest possible power consumption for the possibility of battery operation.

IoT Approach for Air Monitoring
Kousal, Martin ; Frýza, Tomáš
This paper presents a development of a device that can measure air quality parameters and send them wirelessly to the remote server. There, the measured data are processed and shown to the user via user-friendly website. The aim is to create a device with the lowest possible power consumption for the possibility of battery operation. Data will be sent through available Internet of Things network, where user can select between Wi-Fi and LoRaWAN.
