ESP32 Library Developed for Petri Net Embedded in RFID Database

This work has the purpose of presenting the expansion of Arduino Library for PNRD (elementary Petri Net inside RFID distributed Database) and iPNRD (inverted PNRD) to ESP32 platform to reach IoT applications. The original Arduino PNRD/iPNRD Library was updated and receipt ESP32 driver to deal with it. In this approach, the Petri Net model is still based on a matrix equation and defined as the data structure of RFID components, which was restructured internally to assist tag data setup. The result is a highly adaptive, distributed, scalable, and applicable control system that allows an automatic exception identification system ready for IoT. Therefore, this work describes the design, implementation, and validation of a library for ESP32 platform which simplifies the development of new applications that use the Arduino PNRD/iPNRD Library.
