The aim of this master thesis is to propose a system for monitoring and regulation the climate in groups of terrariums using Raspberry Pi platform and with subsequent well-arranged representation through the web server. Each group of terrariums has its own measure and regulation device Arduino NANO that wirelessly communicates with central computer Raspberry Pi. The measured values are stored in the MySQL database in central computer. These values are then graphically displayed on the web page. Limit values for regulation and regulation times can also be set through web page.

This thesis is focused on the design of remote data transmission equipment, without access to mains power. The device will measure the voltage of the gas pipeline and send this information to the operator for processing. Analysis of today's technologies for long-distance transmission and based on the selected technology, the device will be designed. According to selected components, its power supply will be designed with the aim of long-term functionality and continuous operation.

The aim of this master thesis is to propose a system for monitoring and regulating the climate in groups of terrariums using the Raspberry Pi platform and subsequent transparent display through the web server. Each group of terrariums has its own control device that wirelessly communicates with the Raspberry Pi control computer. The measured values are stored in the MySQL database on the control computer. The measured values are graphically displayed on the web page.

Thisdiplomathesisdealswiththedesignofamonitoringsystemforsolidfuelboilers.The first describes the sensors most commonly used in boilers room including a description of the principle of operation. The main content of the thesis is the design of the own boiler monitoring system. First the appropriate structure of the entire system is selected followed by the detailed design of individual parts of the device electronic wiring and selection of suitable sensors. The result of the thesis is the basis for the production of the proposed device and created service program.

This Master's thesis discusses about the measurement of the carbon dioxide concentration in breathing by an optical analyzer using infrared absorption spectroscopy. The method is described with the technical focus on individual components needed for subsequent implementation. A circuit diagram is created to produce Arduino platform devices that serve as hardware to connect and power individual parts and software to create a user environment, followed by a Bluetooth module to transmit measured data to mobile devices where real-time results are presented.
