Stojaspal, Vojtěch ; Skácel, Josef (referee) ; Otáhal, Alexandr (advisor)
The subject of this thesis is design of electronic cigarette with an option to use temperature control function (TC mode), where to achieve requested temperature there is used temperature coeficient of reistancee of material SS316L, from which heating coil is made. There is an option, by using a buttons, to display on 7segment display voltage of batteries, coil resistance, set power and possibly requested coil temperature. For resistance measuring, on which temperature control function is based, there is used a voltage drop on a coil through which a current from a current source flows. This voltage drop is processed by a microcontroller using an A/D converter, where the microcontroller also ensures the operation of the entire device.
