The aim of this thesis is to introduce the principles of detection and analysis of volatile compounds and sensors for this application. Devise and implement a functional pro-totype electrocal analyzer for evaluating the presence of selected volatile compounds and planttion of essential oils. The analyzer is equipped with a user-friendly operation, including displaying the results of measurements and data recording. The functionality of the device to verify, on a sample substances. At the conclusion of the evaluation results.

The main goal of thesis is creation of the automatic growroom and realisation of the controller. The controller will be able for measurement temperature, pH and pH of soil. The soil pH is a measure of the acidity or alkalinity in soils. The other part is about measurement of pH and conductivity. The practical part begun with measurement of pH by laboratory pH meter. These measured figures I compared with figures measured with my pH meter created by my own. The other part describe realisation of my own pH meter and control software. The pH meter was fully managed and also was created describtion for the growroom.

The work deals with building controlling system. It can be divided into three parts. First part describe general theory of smart houses. Second part analysing the task. Last part is realization about.

The subject of the work is an introduction to the problems of linear encoder position. Described the basic principles inductance, capacitive, magnetic and optical position sensors. The thesis also deals with the production technology of sensors and signal processing methods derived sensor. That knowledge is also used for the design concepts for future control circuit device for measuring linear position.

This Master thesis deals with the design and implementation of the spinning head heating for the fibers manufacturing. The first part of this thesis compares the problems of spinning head heating by means of radiant heat and electromagnetic induction. The next part of the thesis deals with the design and implementation of the selected induction heating of the spinning head together with its partial peripherals. The thesis continues with the design of a controlled air flow through the chambre and design of reheating fibers. In the following part of the thesis, functionality tests and partial measurements are performed on the device. At the end, the measurement results are evaluated and compared.

The aim of this diploma thesis is to design and create a prototype of automatic pipetting head that will be useful for pipetting in laboratories after attaching it to a robotic manipulator. In the beginning, a research about various types of automatic pipetting heads was made followed by a device design and component analysis. The prototype was made using 3D printing method and it utilises a peristaltic pump, Arduino microcontroller and Bluetooth interface. A measurement of repeatability and dispensing accuracy was made on the finished device. The results are evaluated in the conclusion.

This thesis deals with principles of measuring of acceleration with commercially available accelerometers and theoretical analyses of measuring of angular speed of rotational motion. Then the proposition of application’s connection controlled by microprocessor and software solution with implementation of serial communication interface is described. The function of the apparatus is examined with experimental measuring and elaborated protocol.

Subject of this thesis is introduction to questions of stepping motors control. The thesis characterizes basic principles some types of stepping motor, their features and control methods. These knowledges are consequently used for proposition of controlling circuit for driving stepping motor using microcontroller.

Presented Diploma thesis is aimed on design and implementation of car diagnostic interface of engine control units EDC. Diagnostic interface provide communication between car and computer by USB interface. User will be able to task commands by developed computer application. For developing application is necessary to get information about used protocols and basic knowledge in car’s hardware. Understanding OBD2 standard and communication protocol CAN, eventually KWP is necessary for design the solution. Main purpose of this thesis is to store enough usable information about car diagnostic for future continuation.
