HS-S62-L NFC inductive read and write module RC522

1. Introduction

The NFC inductive read and write module is generally based on radio frequency induction principle. When an object with the corresponding identification medium (such as RFID tags, NFC tags, etc.) enters the effective induction range (the induction distance varies depending on the module type and power, from a few centimeters to several meters), it can automatically detect and identify the object, trigger subsequent data interaction operations, and is often used in automatic access control systems. When a person carries an authorized inductive card close to the card reader at a certain distance, the access control is automatically opened.

Arduino UNO test results:

After connecting the device and uploading the program to the Arduino UNO development board, the servo will rotate after swiping a card, causing the blocks to move up and down to simulate opening and closing the door.
