The article is dedicated to the justification of the possibility of the use of a long-range radio communication system based on LoRa technology and single-board microcomputers for monitoring and controlling sensors. The architecture of LoRaWAN networks and their advantages, including energy efficiency, wide coverage, and high data transmission reliability, are discussed. The system was tested under real-world conditions, particularly over long distances and in the presence of natural obstacles. The results demonstrated the system's efficiency up to 7 km with minimal data losses, although delays and packet losses occurred at 14 km. An improvement of the data transmission method is proposed to improve performance over long distances with increased transmitter power and the use of larger-capacity batteries. The results of the study demonstrate the suitability of the system for use in real conditions with a wireless signal range of 3–14 km and with the possibility of optimizing the developed hardware and software solution over longer distances without loss of signal quality.
