Introduction: Access Control System - Everything Can Be Configured Via Web UI (IoT)

About: Maker 101; Beginner and intermediate level Maker projects! You can find projects such as "How to" and "DIY" on programmable boards such as Arduino, ESP8266, ESP32 and Raspberry Pi on this channel. The projects…

Hi everyone in this project we gonna make ESP RFID accsess control board with ESP8266 and RC522. Access control system using a cheap RFID reader and ESP microcontroller.

  • Minimal effort for setting up your Access Control system
  • Capable of managing up to 1.000 Users (even more is possible)
  • Great for Maker Spaces, Labs, Schools, etc
  • Cheap to build and easy to maintain

Step 1: Video Tutorial

Minimal effort for setting up your Access Control system, just flash and everything can be configured via Web UI. This control board is great for Makerspace, labs and schools. I made this for my own workshop.

Step 2: Hardware and Tools

Step 3: PCB Gerber File and Schematic

In this project, I have choosen PCBWay. PCBWay is the only way to make this project happen a very low cost and high quality.

Product Detail

Board type : Single PCB

Size : 93.6 x 73.53 mm

Layers : 2 Layers

Total: US $5

PCB Gerber & Schematic

Step 4: Flash Firmware & Web UI


  • First, flash firmware (you can use /bin/flash.bat on Windows) to your ESP -
  • Search for Wireless Network "esp-rfid-xxxxxx" and connect to it (It should be an open network and does not require password)
  • Open your browser and type either ""
  • Log on to ESP, default password is "admin"
  • Go to "Settings" page
  • Configure your amazing access control device. Push "Scan" button to join your wireless network, configure RFID hardware, Relay Module.
  • Save settings, when rebooted your ESP will try to join your wireless network.
  • Go to "Users" page
  • Scan a PICC (RFID Tag) then it should glimpse on your Browser's screen.
  • Type "User Name" or "Label" for the PICC you scanned.
  • Choose "Allow Access" if you want to
  • Click "Add"

Step 5: 3D Case STL

Download the ESP-RFID 3D Case Stl :

  • Layer Height: 0.2
  • Infill: 20%
  • Support: None
  • Material: PLA
  • Time: 04h

In this project, JGAURORA A5S 3D printer was used.
