ESP8266 RFID Inventory Tracker — Log Item Check-Ins/Outs with Timestamp to SD & Serve Inventory Over WiFi Browser

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine a system that automatically logs who borrowed which book from the lab, when it was returned, and shows current availability on any device connected to the same Wi-Fi network—all without a computer. This kit equips you to build precisely that: an ESP8266-powered RFID inventory tracker using the MFRC522 reader, a DS3231 real-time clock for precise timestamping, and a microSD module that stores every event. From CBSE lab asset tracking to a Smart India Hackathon prototype, you create a tool that brings RFID-based accountability into the hands of any maker.

What You'll Build

A standalone RFID terminal that reads tagged items—books, tools, equipment, components—records each check-in and check-out event with a timestamp to a CSV log on an SD card, and simultaneously serves a live inventory webpage. Any device on the local WiFi can browse the current status, see who has a specific item, and review the complete audit trail without needing an app or cloud service. The tri-colour LEDs give instant visual feedback for valid scans, errors, and system ready states.

What You'll Learn

• Interfacing the MFRC522 RFID reader with ESP8266 over SPI and reading MIFARE Classic tags
• Structuring CSV log data on a microSD card—timestamp, tag UID, item name, action
• Serving dynamic HTML tables and status pages from the ESP8266’s web server
• Keeping precise real-time with the DS3231 RTC to stamp each transaction accurately even across reboots

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This intermediate kit is built for CBSE Class 11-12 students who need a working IoT demo for practical records, B.Tech ECE/EEE undergraduates developing a smart inventory project for lab viva or mini‑project submissions, and Smart India Hackathon teams prototyping a library or tool‑room management system. ATL Tinkering Lab mentors will find it a ready‑to‑deploy module for teaching RFID data logging, and it’s a compact solution for IIT, NIT, VIT, or BITS project submissions where real‑time asset tracking matters.
