Add to ORKGThis bachelor thesis deals with a problem of electrical measurement of temperature. It describes a various types of temperature sensors and processing data obtained from these. It describes in short the USB interface and its parameters. It also contains a design of hardware and software solution of thermometer using temperature sensor SMT 160, managed by microcontroller ATmega16 and communicating with PC via USB interface. Designed thermometer also offers possibility to save measured data to built-in memory and later load them from there. Measured data will be also displayed on LCD. Last part of these thesis is design of application for PC, which will serve for displaying measured data and adjustment of thermometer
