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.

HW platform for surveillance over maritime container transport
Roško, Tomáš ; Možný, Radek (referee) ; Musil, Petr (advisor)
The complexity of international transportation is increasing, and with that, the logistics requirements also increase: such as the need to monitor containers’ location or measure inside conditions. Despite these demands, marine transportation faces specific technical problems, such as the need for sending data precisely, often, and with low energy consumption. This paper aims to create a monitoring device that meets the demands of marine transportation. The device combines satellite and mobile networks to control the container location and, at the same time, allows for precise pinpointing of place and availability of access while having low battery consumption. The theoretical part of the paper explains the process of selecting components and justification of the process with regard to market options. The practical part contains a diagram of the connection of the modules and sensors. Next, the design and manufacture of the printed circuit board and custom 3D printed box are discussed. The software part deals with data protocol and the description of the application, which is then tested with a particular focus on measuring and transmitting the values onto the server.
