The goal of the project was to create independent system, which is able to supervise remote site using Ethernet network. It can measure temperature and check state of door magnetic contact. Gained information are sent over network to the cenral node, which is able to present them on web page. In the project are also discussed important network protocols needed for implementation of the system, hardware used for implementation and software of the system.

The main goal of this work is to design an efficient and cheap car-alarm with an electricity consumption not exceeding 1mA in the stand-by mode. The first part focuses on the conception of the car-alarm. As the best option - GPS/GSM car-alarm conception is chosen. Then the design of the switching power supply, communication via RS232 with the GSM module, and GPS module, I2C communication with accelerometer and timer IC, and design of the display module are described. Furthermore, the process of how to code/decode sms into the PDU format is also discussed in this part. The second part provides some basic empirical characteristics of the switching power supply (efficiency, switching frequency etc.). Then the owchart of the main loop is explained, followed by an example of the sms which the car-alarm sends in case a car theft. Explanation of how to set up timer, acceleration threshold and the time between the check of the sms commads is the subject of the next section. Fifth part deals with the installation the car-alarm into a car which is illustrated on the Skoda Favorit example. Total costs and also different cost items are listed just before concluding and suggesting some potential improvements of the device.

This thesis describes the concept and  realization  of embedded system and cloud application, which is designed  for remote monitoring of car subsystems over CAN bus.    There are written several ways of getting information from car subsystems  and process of decoding messages sent over internal car bus.   Data gathering is realised by device based on ESP32, which is sending them to cloud application using wireless networks. Application UI is adapted for mobile devices and serves views containg current and historical gathered data.

The work deals with the measurement of electrical quantities, distribution of data across the Ethernet network into the Internet and intelligent selection of the required values to be transmitted and stored on a central node. The work describes the communication protocols in scale that is necessary for implementation, discussed the requirements for computational resources and microcontroller control is proposed by flowcharts. Attached are source codes in C programming language for microcontroller and PHP scripts for storing and presenting data on Web server.

This project describes the design of a system for remote temperature monitoring of stored a more commodities quantity for the horse-breeding. The main task of this system is the early alert before the fire developed to the spontaneous combustion and continuous monitoring of the quality and safety this commodities. The main module communicates with several autonomous temperature sensors, which are located in multiplie locations. The measured values can be stored on an internal memory, displayed on the display and transmitted with the Ethernet network to the client computer, where it is possible this temperatures to view with in the user program and graphs.

The purpose of this work is to design and implement a device for collecting temperature and humidity from bee hive. The system consists of a measuring unit that contains digital sensors and actuators.The system transmits the measured values wirelessly to the parent unit, which displays the data in a suitable format to the user. The user can monitor the hive parameters and use the actuators to adjust the temperature inside the hive. The whole system then operates autonomously according to defined rules.
