988 Cerradura Nfc RoyaltyFree Photos and Stock Images Circuit Diagram Building a smart door lock using a Raspberry Pi is an exciting and rewarding project that can enhance the security and convenience of your home. Throughout this guide, we have explored the step-by-step process of creating a smart door lock, from choosing the right hardware to programming the Raspberry Pi and assembling the components. Learn how to make ESP32 RFID/NFC Door Lock system, how to use RFID/NFC tag to unlock the door, how to make a security door lock system, how to program ESP32 step by step. The detailed instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help you quickly get started with ESP32. Find this and other ESP32 tutorials on esp32io.com. Here, we'll focus mainly on the newer NFC standard for RFID chips, and its applications to access control within smart door locks. NFC Smart Locks: How They Work The Tech in NFC Smart Locks. As we've covered the science behind NFC tech in the article referenced above, here we'll mainly discuss its applications in Smart Locks.
The system consists of an Arduino Uno microcontroller, an MFRC522 RFID/NFC reader, an SPDT relay, and a 12V DC solenoid door lock. The RFID/NFC reader reads the UID of the tag and compares it with a pre-defined UID in the code. If the UIDs match, the system triggers the SPDT relay to unlock the door for a pre-defined time period, allowing access.

For example, only the person with the right information on his card is allowed to enter. In this tutorial, we have multiple RFID tags, each with its own Unique Identification (UID) but only one card will be granted access. RFID-RC522 Pin Layout
