RAIN RFID Smart Storage Solution

This project developed a RAIN RFID based smart storage system for bottle detection and relative fullness estimation. Using commercial RFID readers and passive tags, this team collected RSSI, phase, and frequency response data to analyze how RF signals vary with liquid levels. To improve robustness, they introduced reference tags to mitigate environmental variation and signal drift. Through controlled cabinet experiments, they addressed challenges such as interference and material effects, demonstrating a low cost and scalable solution for multi object sensing and intelligent storage applications.
