Transmitter and receiver for remote data transmission
Zimčík, Václav ; Toman, Marek (referee) ; Huták, Petr (advisor)
Bachelor thesis is focused on the construction of a multichannel thermometer with wireless data transmission. The device will be able to receive data from multiple transmitters, to which multiple temperature sensors will be connected, to one receiver by wireless transmission at a frequency of 433MHz, and then the device will display this data on a display using selected components and algorithm.

Very low temperature measurement
Mráz, Dominik ; Harabiš, Vratislav (referee) ; Chmelař, Milan (advisor)
This bachelor thesis is focused on low temperature measurement, respectively on temperature sensors classsification, their accuracy, temperature range and linearity. It deals especially in use of these sensors in cryogenic applications. It contains temperature sensor block diagram, including the description of each block. It also contains schematic designs with description of each design’s function, components and the reason why it’s used. Additionally the realization of the temperature sensor is described and it’s testing.

Design of thermal system for accurate temperature stabilization using Peltier thermoelectric modules
Motl, Jakub ; Trčka, Tomáš (referee) ; Macků, Robert (advisor)
This master’s thesis describes design procedure of a heat-regulating system to stabilize its temperature using a Peltier module. The implementation uses eight-bit microcontroller ATmega16 made by company ATMEL for the local and remote control system. The temperature sensors communicate with the microcontroller by serial SPI interface. To display user data, it has a DEM16217SYH type character LCD display with HD44780 control circuit. To collect data from the cooling areas of Peltier module, accurate ADT7320 temperature sensors are used, made by company Analog Devices. The Control of the Peltier module happens in two points of the electrode system and a bistable hysteresis software regulator is used. The first part summarizes the theory, which concerns with the design. Next part concerned with issues of the Peltier module, overview of temperature sensors, description of the microcontroller, the display unit and the used regulator. Last part describes the hardware and software implementation.

Very low temperature measurement (to -160 of degrees Celsius)
Vlček, Josef ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
his semestral thesis deals with measurement of low temperatures (down to -160 degrees Celsius). This thesis describes basics of cryotherapy and its practical implementation. It also deals with different types of temperature sensors which means theoretical description of their work, thein advantages and disadvantages. The main goal is to put a recommendation of which of this sensors is the most suitable for practical implementation of the thermometer.
