Abstract:

This diploma work describes the design and realization of prototype system for measuring temperature and its connection to Ethernet network. The core of system is Microchip’s PIC 18F67J60 microcontroller on which runs application for measuring temperature with DS18x20 sensors and application for data transfer to the PC using the Ethernet protocol. The main purpose of the unit is temperature measurement, automatic detection of connected sensors and transfer the measured data using SNMP to PC where data are stored and displayed in graphical form.

The aim of the diploma work was to realize the most universal an affordable system for temperature measuring and simple supervising and storing of measured data through personal computer.
