Introduction

Security is significant to deal with for any place. Whether, enterprises, banks, exhibition halls, or homes, it’s critical to make each place secure. Along these lines, today in this tutorial, we are making RFID Based Security Doorlock System using RYRR10S. Controller Door Locks allow Wireless Control. This implies one can open or lock their entryways with only a single tick from their cell phone or act out of control. It replaces the traditional lock framework and gives a much safer lock.

For the making of this circuit, we are using the RYRR10S RFID module. Radio Frequency Identification that is abbreviated as RFID, utilizes electromagnetic fields to automatically recognize the tags. The RFID tag stores an extended range of information in it. The RFID tags powered the RFID reader to read. RFID emits the radio waves to emit the signal back from the tag.

Features of RYRR10S RFID Module

  • ST CR95HF NFC/RFID Engine.
  • Supports Near Field Communication (NFC) ISO/IEC 18092.
  • Completely Integrated Protocol Handling for ISO/IEC 15693, ISO/IEC 14443A, ISO/IEC 14443B.
  • NXP MIFARE® Classic compatible
  • Designed with PCB integrated antenna.
  • UART / SPI Interface optional.

Working Explanation

In an RFID entryway lock access control circuit, the credential of the user contains unique data known as a tag. At the point when the user comes extremely close to a reader, the reader finds the data on the client’s RFID tag and sends it through radio antennas and transceivers to approve the tag in the entrance control system. When the reading gets completed, the system will either acknowledge or deny the request to open the entryway (here in our case, solenoid lock).

Applications

  • We can use it in our home security system.
  • We can use it in offices to only allow the working faculty.
