HZ1050 RFID Reader with Arduino, interfacing and programming

HZ1050 RFID Reader

Introduction:

HZ1050 RFID Reader- In this tutorial, you will learn how to use the HZ1050 RFID Reader with the Arduino and display the ID number of any RFID tag. I don’t know if the HZ1050 RFID Reader is as popular as the MFRC522 RFID Module. I have been using the RFID readers particularly the MFRC522 for quite a long time in different projects, which you can find in the related projects section given below.

This is my first tutorial on the HZ-1050 RFID reader. I came to know about this RFID reader through my friend Chimpo and decided to give it a try. A very cool thing about the HZ1050 RFID reader is that it does not need a lot of wires, this supports serial communication, so, you will need a maximum of 3 wires to connect this module.

Without any further delay, let’s get started!!!

HZ1050 RFID Reader Pinout:

On the right side you have pins for the serial communication and on the left side you have pins for the SPI bus. In this tutorial you will go with the serial communication. We will be using pins available on the right side of the HZ1050 RFID Reader Module.

HZ1050 RFID Reader interfacing with Arduino:

HZ1050 RFID Reader

you need only three wires to connect the HZ1050 RFID reader module with the Arduino. connect the 5v of the RFID reader with the Arduino’s 5V, Connect the GND pin of the HZ1050 with the GND pin of the Arduino, and finally connect the TXD pin of the RFID reader with the D2 pin of the Arduino. So, that’s all.

Everything is quite clear, on the right side we have the antenna where we swipe the RFID Card or Tag, in the middle, we have the RFID reader itself, and on the left side we have the Arduino Nano. You can follow the same exact connections using the Arduino Uno. Now, finally, we can start the programming.


Before, you start the programming; first of all, make sure that you download the wire.h library.

HZ1050 RFID Reader Arduino Programming:

HZ1050 RFID Reader Arduino code explanation:

You can use the Arduino’s default serial port, but as I always say, never use the Arduino’s default serial port, it should only be used for the debugging purposes. As in Arduino Uno and Arduino Nano, we have only one serial port, so using the SofwareSerial library we can define multiple serial ports. So this is the reason I started off by adding the SoftwareSerial library.

#include <SoftwareSerial.h>

#include <Wire.h>

SoftwareSerial HZ1050(2, 3); // RX and TX

int i, j;

long value;

In the void setup() function, we simply activated the RFID reader and the serial communication. For now, I am using the same baud rate 9600.

void setup()

{

HZ1050.begin(9600);    // start serial to RFID reader

Serial.begin(9600);  // start serial to PC

}

In the void loop() function, we simply read the RFID card or tag and added an if condition to check if the desired card or tag is present.

void loop()

{

value = NULL;

//Serial.println(value);

if (HZ1050.available() > 0)

{

value = NULL;

for (j = 0; j < 4; j++)

{

i = HZ1050.read();

value += ((long)i << (24 – (j * 8)));

}

while (HZ1050.available() == 0) {};

Serial.print(“UID:”);

Serial.print(value);

Serial.println();

if (value == 9157613 || value == 6028023) // Your UID’s

{  Serial.print(“Accepted”);   // if correct uid is present do this…

Serial.println();

//value = NULL;

}

else {   Serial.print(“Denighed”);

delay(200); // if incorrect uid is present do this…

Serial.println();

// value = NULL;

}

}

}


HZ1050 RFID Reader Testing:

I uploaded the above program, opened the serial monitor, swiped my card, and I could see my RFID card number.

So, that’s all about the HZ1050 RFID Reader. I hope you have learned something from this article. If you have any questions regarding this project or any other project, let me know in a comment.
