Utilization of various sensors for data collection for immediate or later evaluation is the current trend in the area of industrial technology. Our solution of the universal 1-wire module provides a single interface for sensors with different communication interfaces, while it still communicates with the standard 1-wire bus controller. The main advantage of this solution is the ability to utilize a sensor from a large variety of available sensors with a standardized communication interface. As a platform for the development of such module, STM32-based microcontroller was chosen. The goal was to design and implement a universal low-power 1-wire bus module with a fully implemented 1-wire standard. The individual sensors or the nodes of the communication network are connected in parallel. One of the economical solutions is the usage of a 1-wire communication network that requires only 2 physical wires. Their type, the used communication protocol, plays an important role in the parameter of their complexity. Sensory networks are part of a solution to monitor the required physical variables in the area of interest.
