Wireless signal transfer from temperature sensors
Hulanský, Jozef ; Drexler, Petr (referee) ; Roubal, Zdeněk (advisor)
The main goal of this bachelor’s thesis is to design a device capable of measuring temperature to prevent danger in critical hot areas of high voltage electric distribution boxes. Hardware platform is focused on the Atmega8 chip from ATMEL Corp. factory. In this dokuments is elaborate the Zigbee wireless communication protocol, some types of temperature senzors and power system. The second part of this dokument are about the particular solution of measuring temperature and carrying values with wireless modules. This thesis also contains schematic and printed circuit board with pictures of system in work. In the end of this document are indicated experiences in the development of work and other possible solutions in the future.

Location visualization of sensor units
Hulanský, Jozef ; Verner, Lukáš (referee) ; Komosný, Dan (advisor)
This master thesis deals with wireless sensor network with protocol IPv6. In the begining there are explained the priciples of communication in wireless sensor network, and based on this teories are configured a wireles network with predefined development kit. Furthermore, by using geographic coordinates, positions of the nodes are displayed on a website, what is a part of this thesis. On this website are also presented the measured values from sensors. For saving all informations and measured values about each nodes was used remote MySQL server. Communication between this server and 6LoWPAN network provide Perl script which is runs at periodical intervals. With this method automatization of the whole system are ensured.
