Secondary abstract:	Every process control begins with measuremets of current state and adjustments that depend on measured values. For the purpose of this thesis an embedded system was designed, that can measure both temperature and relative humidity. The system is able to provide its measurements to the monitoring or controlling system. The main component of the embedded system is a PIC 16F1827 microcontroller connected to a RS-485 driver that provides for serial communication features, digital sensor HYT 271 for temperature and humidity measurement and a RC converter (RC – electrical resistance to electrical current). A complementary application for configuration of the embedded system was also developed using the C# programming language. In the final phase, our embedded system was connected to a HMI display by RS-485 standard and Modbus protocol. The display used for this purpose was a Fatek FV035ST-C10, which acted as a bus master, displaying the measurements taken by the embedded system.
