Solution Overview

Problem

The existing methods for preparing a parking arrangement with automatic vehicle detection systems are laborious and prone to errors, requiring manual input of identification codes into a database, which can lead to misreadings or incorrect associations, especially when the layout changes.

Innovation Solution

The use of parking sensor modules with RFID identification circuits allows for wireless reading of identification codes, enabling automatic or semi-automatic input into a smartphone, which then synchronizes with the central computer, reducing errors and streamlining the process by utilizing low-frequency RFID for precise node positioning and UHF radio links for communication.
