Accumulator tester with ESP32 module
Dresler, Jan ; Musil, Petr (referee) ; Lattenberg, Ivo (advisor)
This thesis focuses on design of printed circuit board and programming of ESP32 module. This module communicates with discharging circuit which allows testing of battery properties. With help of voltage and current sensors it is possible to test and print results of battery on display. The testing device also allows control over web user interface thanks to ESP32.

Smart Home System
Hájek, Jaroslav ; Lattenberg, Ivo (referee) ; Krajsa, Ondřej (advisor)
This work deals with connecting remote devices measure data of various types from physical quantities such as a temperature, a humidity to data displaying CPU or memory usage of the system to the user. The system uses Blockly to controlling logic and dependencies between devices. In the work is used lots of technologies for examples: MQTT, Websockets, GSM, Lightweight Mesh and others. The system is based on microservice which named is Flask. Flask service is an application interface for HTTP services of Python programming language. This can provide measured data by graphs and predefined components for viewing data. For controlling system was used single-board computer Raspberry Pi with a multitouch 7-inch display.
Wireless transmission of diagnostic data from the vehicle
Tuchyňa, Juraj ; Lattenberg, Ivo (referee) ; Krajsa, Ondřej (advisor)
The main purpose of this project is to analyse used protocols in vehicles available under the OBD II specifications. In the project we will also focus on processing diagnostic data. We will design device for vehicle diagnostic. This device will be able to send processed data on external web server via Internet network. Obtained data will be saved on data server. Building of functional receiver will be the major part of master´s thesis.
Weather station
Rimeg, Martin ; Číž, Radim (referee) ; Lattenberg, Ivo (advisor)
This work deals with the development of a meteorological station for measuring temperature, atmospheric pressure, humidity and light intensity. The main feature of the device is the ESP 8266 module, which records the measured values and sends information to the server. Part of the work is PCB design, selection of suitable sensors and application development for display of measured values. The description of the solution was preceded by the theoretical processing of development topics.
Low-energy Security Device with (Espressif) ESP8266/ESP32 Module
Ondráček, Petr ; Lattenberg, Ivo (referee) ; Škorpil, Vladislav (advisor)
Bachelor's thesis discusses the design and realization of low-energy security device using Wifi module ESP32. The device will detect the opening of door/window/space by using magnetic contact and this event will be reported on appropriate cloud service and by e-mail. The theoretical part is focused on the Internet of Things problematics, cloud services and description of individual components of the final device. Second part of thesis is focused on designing of the linkage scheme, control program and calculation of power consumption of the device. Third part is already focused on practical realization of the designed device, designing and creation of printed circuit board and security box, programming, creation of the cloud channel that will visualize collected data and measurement of power consumption of the final device.
Front-end frameworks for ASP.NET Core web applications
Kozhukhov, Konstantin ; Harár, Pavol (referee) ; Lattenberg, Ivo (advisor)
In this bachelor thesis I deal with design and implementation of a web application servingas information system for storage of electronic components. The first two chapters ofthis work deal with the theoretical analysis and description of technologies that will beused in the application, while the last chapter is dedicated to implementation. The goalof the resulting program is a simple demonstration of the use of the platform ASP.NETCore with a framework DotVVM.
Temperature Sensor Using (Espressif) ESP32 Module
Roško, Tomáš ; Lattenberg, Ivo (referee) ; Škorpil, Vladislav (advisor)
This bachelor thesis focuses on construction of battery powered temperature sensor with Wi-Fi module ESP32 with the possibility of connection to any analogue industrial sensor. The construction of module emphasizes on minimal battery power consumption with taking into account the longest possible duration per one charging battery cycle. It is also stressed on the way of storing measured data and realization of website, which presents those data to the end user in a comfortable manner. The theoretical part describes Internet of Things, accentuates its history, usage and security. The chapter also covers vast possibilities of application of different sensors and their usage in both industry and ordinary life. The Internet of Things chapter is concluded with description of most used communication technologies and protocols. The practical part is concerned with construction of temperature sensor with ESP32 module. It is divided into three main parts. First part deals with the specification of requirements and the design of the device. It also takes into account the choice of best possible way of powering the device by battery and calculation of battery life. Chapter also discusses individual parts of the whole device, such as the choice of temperature sensor or the solution of connectability of industrial sensors. The second practical chapter deals with the realization of device, both in hardware and software way. Hardware part describes realization of the printed circuit board and its 3D printed coverage, whereas software part sheds light on the programming of the device and how the web presentation works. The final chapter presents two main things: how was the module tested and complete financial calculation for the whole project.
Transistor tester connectable via USB
Skopalík, Daniel ; Krejčí, Jan (referee) ; Lattenberg, Ivo (advisor)
This thesis describe development and realization of transistor tester based on AtMega microcontroller. Developed equipment should be used by DIY users or students in university workshop to verify transistor functionality and measure basic characteristics. Equipment should be easily manufacturable in a piece quantity with reasonable costs.
