IoT system for gardening
Mlčák, Petr ; Kiac, Martin (referee) ; Caha, Tomáš (advisor)
The thesis deals with the design and creation of a weather station suitable for gardeners. The created device is able to measure temperature, pressure, humidity, amount of precipitation, wind speed and direction, UV index and also temperature and soil moisture at several depths. The weather station is powered by a battery with auxiliary charging from a photovoltaic panel. The thesis is divided into several parts. The theoretical part describes the individual physical principles of measurement of the considered physical quantities. Subsequently, a comparison of available sensors is made and then a final selection is made. The third part deals with the design and implementation of the hardware circuitry including the creation of the PCB. In this section, the holders of each sensor are also designed for printing on a 3D printer, which are then printed. The fourth section deals with software design issues, which is described in more detail. Finally, the whole weather station is assembled, wired and the functionality of all components is verified by sending the measured data to Thingspeak.

Device for measuring fluid level
Mlčák, Petr ; Dvořák, Jan (referee) ; Sikora, Pavel (advisor)
Thesis focuses on device design and realization of battery powered fluid level meter with intended use in underground tanks. Device can be configured to set the measurement and send data to cloud periods. Device is able to send warning emails if low battery voltage is detected and also send warning emails if measured water level is outside the range set by user. Theoretical part focuses on some of nowadays used measurement methods used in water level measurement. This part also includes a brief description of bus and protocols used by final device. Next part is about design and realization of device. In this part are described some used components, analyzed some parts of software and also design and realization of hardware including final design of device.
