Here I have interfaced RFID-RC522 Module with NodeMcu ESP82.

In this tutorial, we will learn how to Connect RFID to PHP & MySQL Database with NodeMCU ESP8266.

Damals hatte ich das Reader-Modul, welches die ausgelesene Tag-ID der RFID-Tokens einfach auf seiner seriellen Schnittstelle ausgibt mit einem Attiny 2313 gekoppelt, der die IDs mit einer Liste auf seinem EEPROM abgleicht und entsprechend einen Relaisausgang schaltet. Den RFID-Reader hatte ich euch bereits in meinem Artikel RFID-Türöffner vorgestellt. You can easily record the data in a database. You of course can find other palaces to use this device. There are very cheap RFID readers (like RC522) around for a while and bringing them together with our great hero esp8266 WiFi chip seems to me a good idea.

Publishing RFID tag with wifi is a great idea and there will be lots of usage areas.

The purpose of this post is to get you up and running with this device using the Sparkfun Thing board and Arduino IDE. This is an introductory post on getting started with ESP8266 WiFi Module/Microcontroller used in IoT applications.

Getting Started with ESP8266 WiFi Module.

Or production equipment that alert maintenance For example, a new building development project could be fitted with sensors to automatically adjust heating and lighting.

The Internet of Things is the concept of everyday objects – from industrial machines to wearables – using built-in sensors to collect data and act on this data over the network.

It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.

ESP8266 is a highly integrated chip designed for the needs of a new connected world.

With that being said, I encountered a problem. I've been working on a project for quite a while now, which involves the ESP8266 NodeMCU (v1.0), as well as two SPI Modules: ENC28J60, and RFID-RC522.
