Weather measurement
Chovanec, Jan ; Havránek, Zdeněk (referee) ; Bejček, Ludvík (advisor)
The achievement of this thesis is to design functional equipment which is able to measure the basic meteorological variables as air temperature, humidity and barometric pressure. In order to measure relative humidity completed with temperature, an intelligent sensor manufactured by Intersema Inc., MS5534B, was chosen. Relative humidity is measured by a capacitance sensor Humirel HS1101LF. The measured data are stored in anon-volatile memory. Data can be downloaded to a computer file via serial port or they can be online displayed on the computer screen via the wireless Bluetooth connection. Because the equipment is supposed to be used for the external measurement without the connection to electricity, low power consumption was considered as a most important parameter as well as good weather protection.

Weather Station
Beneděla, Pavel ; Šedivá, Soňa (referee) ; Havlíková, Marie (advisor)
This thesis deals with conception of proposal and implementation of a weather station. Weather station is composed of three main parts which are measuring station, showing station and USB wireless receiving module. Measuring station measures basic meteorologic variables and sends measured variables through wireless communication. Showing station is designed to present measured data with graphics user interface and generate data for a web server.

Microcontroller based system equipped by MEMS barometer
Gábik, Matej ; Šír, Michal (referee) ; Bradáč, Zdeněk (advisor)
The aim of this work is to design micro-electro-mechanical system with microcontroller barometer. The work deals with explaining the problems of pressure measurement, by selecting the appropriate sensor and the actual design and construction of the facility. Data from the sensors are evaluated using a microcontroller in real time on the display.

Logging station for humid environments
Pavlík, Jan ; Roubal, Zdeněk (referee) ; Szabó, Zoltán (advisor)
This thesis is about the design of a meteorological station deployed in a wet environment and its construction. The station will be used for measuring meteorological instrumentation in caves, because of that the station was designed to minimize its power consumption. Firmware was designed, to allow remote control of the station. A major part of the thesis is concerned with selection and description of the sensors and components used. Near the end of the thesis the control algorithm, communication interface and construction of the device is described.

Weather station for smart home system
Mitter, Martin ; Burian, František (referee) ; Šedivá, Soňa (advisor)
This semesterly thesis deals with designing of weather station whose task is to provide via wireless data transfer on Wi-Fi network up-to-date information of measured temperature, barometric pressure, relative humidity, ambient light, wind speed and directions to smart home system, whose job is to store the values, creates its visualization for users and based on the data regulates the systems. The work describes the selection of suitable sensors for those variables and the design of the structure of the hardware part of the weather station. Theoretical parameters of the proposed solution are compared with the competition. Then the whole system is build and tested.

Návrh a realizace mobilní meteostanice
CHYTRA, Petr
This diploma thesis deals with the design and implementation of a portable weather station which allows you to measure air temperature, relative humidity, atmospheric pressure and especially the concentration of suspended particles in the air on which the work is focused. The portable weather station must be compact and have its own power supply. Part of the work is also the implementation of own measurements in selected localities.

Meteorological station system
Čada, Jan ; Balík, Miroslav (referee) ; Lattenberg, Ivo (advisor)
This bachelor thesis deals with the design and implementation of a online meteorological station system, which consists of individual weather stations that communicate via the Internet with the server. The first part of the thesis discusses the principles of measuring major meteorological variables and deals with the selection of suitable sensors for measuring temperature, atmospheric pressure, humidity, wind speed and rainfall. In the practical part, one of the weather stations based on Raspberry Pi Zero microcomputer is designed and realized. As a complement to the measured data, the station includes a camera that captures the view from the site where the meteostation is installed. 3D printing is used to realize most of the mechanical parts, it has the advantage of speed, accuracy and easy reproducibility. For the measurement of temperature, pressure and humidity, a combined sensor BME280 from Bosch is used, which is placed in a small Stevenson screen. The wind speed is measured by a cup anemometer whose rotation is sensed by an integrated Hall sensor. The output pulses are then counted using the PCF8583 circuit, which has an I2C interface for reading the values with a Raspberry Pi microcomputer. Special attention is paid to the construction of a custom calibratable tipping bucket rain gauge with a resolution of 0,5 mm, whose mechanical motion is also sensed by a Hall sensor as in the anemometer. The reading of the data from sensors and sending it to the server is handled by a Python script. For storing and presenting data to users, a custom server solution based on LAMP webserver is implemented, its source codes are written in PHP, HTML, JavaScript and CSS. In addition to the web interface, which displays the data in graphs, the measured data can be also presented to the user via an application for mobile devices based on Android. The application was developed in C# using the Xamarin framework in the Microsoft Visual Studio development environment. Among other things, it implements a widget for quick access to the measured values directly from the home screen. In the final part of the thesis, interesting findings obtained by observing the measured values are mentioned.

Datalogger or building constructions
Hendl, Adam ; Streit, Jakub (referee) ; Bradáč, Zdeněk (advisor)
The bachelor thesis deals with automated measurement of temperature, humidity and pressure in building structures. In the section dedicated to my work is primarily a process as I progressed in implementing the task. The next section describes the parameters of the components used to implement the measurement and data storage. This work also includes a design of a printed circuit board that includes auxiliary and measuring circuits.

Design of a new iontometer with wireless communication and weather station
Kadlček, Václav ; Hrabina, Jan (referee) ; Roubal, Zdeněk (advisor)
This diploma thesis deals with the design of an autonomous system for the measurement of the concentration of atmospheric ions. This is a new version of the already asembled Iontmeter by UTEE FEKT. Unlike the previous version, this new one should be completely independent of electrical network and configurable even without a PC. The design includes increased water and dust resistance, wireless transmission from the weather station and its own temperature, atmospheric pressure and relative humidity sensor.
