The principles of construction and parameters of sensor network interfaces are characterized,which are characterized by a large number of sensors and a considerable distance of informationtransmission to the central point or server. The majority of sensors on the Internet of Thingssystem have little performance. In this case, the sensor network requires protection againstinterference and interference. Only cable networks are eligible for this group of sensor networks.Sensor networks are most suitable for cable industrial networks. The analysis and comparison ofindustrial cable network interfaces shows that the most appropriate requirements are the RS-485interface and its derivative interfaces. All industrial network cable interfaces are very good atsatisfying one requirement and not meeting the other. Passive fiber optic network is the mostsatisfying. It is convenient to use passive fiber optic (PON) technologies to build such a network.There are currently quite a number of passive fiber splitter technologies that can be used to createa multipoint trunk or ring passive fiber optic network. Networks with fiber-optic encoders, whichalso have a large number for measuring different physical parameters, are very convenient andefficient. For the exchange of information in these networks, it is convenient to use the 1- wireinterface protocol, which is supplemented by the use of frequency signals. Such networks will belightweight and compact over time on moving objects and in hazardous conditions. The materials of the article are of interest for carrying out the educational process in universities, in particularat the Kyiv University named after B. Grinchenko.
