Product Description

125Khz RFID Reader Module RDM6300 UART Output Access Control System for Arduino

Description:

RDM630 series non-contact rf ID card special module, adopt advanced rf receiving circuit and embedded microcontroller controller design, combined with efficient decoding algorithm, complete EM4100 compatible type ID card data reception.Has received high sensitivity, small work current, stability higher characteristic, is suitable for access control, attendance, charge, security, patrolling, etc all kinds of rfid applications.

Output format into hexadecimal beginning frame + ID check code + code + stop frame, such as the Numbers on the ID Tag0008565187And the output as shown below

The For arduino users abroad commonly used RFID read card matching module, can read 125 k EM4100 RFID card series.The module is easy to use, after the power supply serial ports connected the For arduino board, when there is a range of RFID card into the card read, module via the UART directly put the card sent to the For arduino.With a relay module connected to the For arduino can implement a simple access control.

The test code:

String comdata = “”; Void setup () { PinMode (2, the OUTPUT); PinMode (3, the OUTPUT); DigitalWrite (2, HIGH); DigitalWrite (3, HIGH); Serial. The begin (9600); } Void loop () { DigitalWrite (2, HIGH); DigitalWrite (3, HIGH); While (Serial. The available () > 0) { Comdata + = char (Serial. The read ()); Delay (2); } If (comdata. Length () > 0 && comdata = = “0500 addf1443”) { While (comdata. Length () > 0) { DigitalWrite (3, LOW); Delay (100); While (Serial. The available () > 0) { Comdata + = char (Serial. The read ()); Delay (2); } Comdata = “”; } } Else if (comdata length () > 0) { While (comdata. Length () > 0) { DigitalWrite (2, LOW); Delay (100); While (Serial. The available () > 0) { Comdata + = char (Serial. The read ()); Delay (2); } Comdata = “”; } } } Package Included: 1 * RFID Reader Module
