What is NFC-WiFi?


It is a NFC reader with WiFi!
This project joins a NFC reader(PN532) to a WeMos D1 Mini to allow for WiFi access.
What can you do with this?

  • Toggle a IFTTT event or send a MQTT message with a NFC tag

  • Integrate into home automation systems

  • Send notification when scanned

  • And much more

Where do I get one?

Want one? They are on Tindie now!


I sell on Tindie




The enclosure is 1.8in x 1.85in x 0.8in(46mm x 47mm x 20mm) 3D printed with PETG so should hold up to outdoors to some extent however if it’s going to be outdoors you’ll want to seal up the hole where the USB connects.

There are also some diviots to ease in mounting via screws, or you can use double sided tape to attach it to a surface.

There is a lid that can slide off to allow you to remove the boards from inside. The hole is designed for the USB cable I send with board/enclosures when purchased but should fit most micro-USB cables.
