ARM-Based Universal 1-Wire Module Solution

الملخص EN

Sensory networks are part of a solution to monitor the required physical variables in the area of interest.

Their type, the used communication protocol, plays an important role in the parameter of their complexity.

One of the economical solutions is the usage of a 1-wire communication network that requires only 2 physical wires.

The individual sensors or the nodes of the communication network are connected in parallel.

The goal was to design and implement a universal low-power 1-wire bus module with a fully implemented 1-wire standard.

As a platform for the development of such module, STM32-based microcontroller was chosen.

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.

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.
