An Arduino ESP8266 RFID door-relay authentication system with a logging back end.
I want people to be able to contribute to this project if you have any ideas. Please feel free to fork as well!
- Google Sheets Integration with Real-Time logging using IFTTT
- Long range (Range of wifi and connection to the arduino board)
- Secure: Exponetial bruteforce mitigation, Arduino board is in-accessable from the RFID reader (about 10 feet of distance between the circuit boards)
- Cheap: Only costs around $50 for the entire build rather than hundreds of $ for a 'professional installation'
- Adafruit ESP8266 : $20 (+ or - $5)
- RFID Reader : $7 or cheaper
- Soldering station / skills : (Can be used at local maker space or university; if not, buy one that isn't like $40 ($80+ range is good), it'll make your life easier)
- Cable (For distancing the card reader from the board for maximum security; Cat 5e works very well) : (You probably have it laying around and if not you could find some at a local electronics recycling center)
- 5v Relay Module : $2 - $3
- PCB Boards : $10 or less (OR you can order the pcb file with a gerber file; more details below)*
- Spare RFID Cards / Rings : $20 for 100 (or less)
- Time, Patience and self love and a good soldering iron vent system! You don't want solder poisoning do you?!
- This one might work if you don't live by a microcenter Relay

First gather all the parts and make sure you have about an hour of time to assemble/solder everything.
