Contact SupplierRadio Frequency Identification (RFID) Card Readers provide a low-cost solution to read passive RFID transponder tags up to 2 inches away. The RFID Card Readers can be used in a wide variety of hobbyist and commercial applications, including access control, automatic identification, robotics navigation, inventory tracking, payment systems, and car immobilization. The RFID card reader read the RFID tag in range and outputs unique identification code of the RFID tag. The RFID reader can interface to microcontroller or PC and the unique identification code of the RFID tag received by the RFID reader is send through serial at baud rate of 9600. In this project RFID connected to 8051 through serial interface. The main purpose of the project is to provide automation for mining industries. In all mines, coal will transfer through vehicles or Lorries. All vehicles information proceeds by manual. But in this case lot of chance to manipulate. In this project each vehicle established with RFID cards, If RFID tag detected then microcontroller validates tag and gate will open. If microcontroller detects invalid tag then buzzer will come and gate will not open. In this project 7805 is a regulator and it avoids noise spikes in power supply. RFID modem is connected to microcontroller through serial port. These RFID modem works under 9600 or 4800 baud rates. 16X2 LCD connected to microcontroller through digital I/O lines.
