Abstract: One of the most important parts in scientific researches is realization of reliable monitoring system. In this article is presented one possibility for using the microcontroller PIC16F84A as a controlling unit, and interface with the Dallas DS1820 1-Wire™ Digital Thermometers. Special software application for program service of this device is developed in visual programming environment DELPHI . The real experimental device, which uses this monitoring system, is a solar drying-room system. The interface for data receiving is COM port of the computer. After receiving, the data are archived in database format. The present monitoring device is applicable for different systems after some small changes.
