Temperature and humidity monitoring devices with wirelless communication
Horváth, Michal ; Baštán, Ondřej (referee) ; Bradáč, Zdeněk (advisor)
The diploma thesis is about designing device which monitors temperature and humidity. In the first part of thesis are explained basic terms, importance of key variables and on market offered products are described. After that the thesis describes device concept design with schematic designs. From designed schematics are described printed circuit board designs. Next part is about device commissioning and correction of errors caused by incorrect design. Last part is about program designing and device testing.

Wireless sensoric network for hop drying facility
Čapek, Lukáš ; Čech, Jakub (referee) ; Šnajdr, Václav (advisor)
The purpose of this project is to build a wireless sensor network for measuring temperature and relative humidity in hop drying facility. This is a monitoring device, consists of several sensor units and one control and display unit. Display unit coordinates a whole network and can display data on LCD or download collected data to PC. Sensor unit measures a relative humidity, temperature, battery voltage and transmits data to display unit. Units contain a transceiver which operates in ISM band 868 MHz. Circuits are driven by 8-bits microcontroller Freescale.

Optimalization and measurement of transport experiments on graphene field effect transistors
Urbiš, Jakub ; Pilch, Jan (referee) ; Bartošík, Miroslav (advisor)
This thesis deals with the automation of transport experiments on graphene using the graphical programming language LabVIEW. Specifically, the experiments with graphene relative humidity sensors are based on: a two-point graphene structure, a two-point structure of SiO$_2$ and a four-point graphene structure in the form of a Hall bar. In all of these experiments, relative humidity, input electrical parameters, SPM measurements, and macroscopic transport properties are measured simultaneously. The program DeviceManager developed in framework of this thesis simplifies the implementation of these experiments.

Sensory array for home automation
Bastl, Michal ; Lamberský, Vojtěch (referee) ; Vejlupek, Josef (advisor)
Bachelor thesis Sensory array for home automation describes the design of a simple system for measuring air temperature, relative humidity and light levels in the room. The aim is to design measuring units which will be able to communicate with the parent unit through the RS-485 fieldbus. Parent unit will be designed to allow the transfer of data to PC via the USB bus.
