This repository contains the implementation of the research paper "A Cloud-based Grocery Tracker Management System using Radio Frequency Identification", published in the 2023 International Conference on Sustainable Computing and Smart Systems (ICSCSS).
The project addresses the critical issue of food waste and health risks associated with expired dry groceries. By leveraging RFID technology and Cloud Computing, we developed an autonomous IoT system that tracks grocery lifecycles, estimates remaining quantities, and synchronizes real-time data to a web-based management console.
- Automated Expiry Management: Developed a mathematical model to calculate the remaining shelf life by synchronizing with NIST time servers for high-precision date tracking.
- Dual-Layer Architecture: Engineered a seamless bridge between physical hardware (IoT Device) and a cloud-based backend (Firebase BaaS) for real-time data persistence.
- Inventory Digitization: Implemented RFID-based tagging to preserve critical metadata (manufacturing/expiry dates) that is typically lost when transferring groceries to secondary containers.
-
Edge Computing Efficiency: Utilized an embedded microcontroller for independent data processing and Wi-Fi-based cloud synchronization, ensuring the system functions with minimal power consumption (
$< 5W$ ).
The system is composed of two primary modules:
- IoT Edge Device: Built on NodeMCU, it facilitates physical interaction via an RFID reader and an embedded LCD. It performs local data acquisition and handles bidirectional communication with the cloud.
- Web Management Console: A centralized dashboard for stakeholders to input grocery metadata, monitor inventory health, and receive automated alerts regarding approaching expiry dates.
