JT308 USB Proximity RFID Card Reader 125KHz

Description

What it is

The JT308 is a RFID card reader for proximity sensor, connectable via USB. It is designed to operate at 125KHz and read compatible RFID cards.

Features

• Connection: USB
• Frequency: 125KHz
• Type: Proximity Sensor

What it is for

The JT308 can be used to create RFID-based access systems, such as door or restricted area access control. It can also be integrated into security and identification projects. It is compatible with Arduino and IoT platforms.

Tutorial: How to use JT308

The JT308 is a USB RFID reader for proximity sensor, ideal for security and identification projects. It serves to read 125KHz RFID cards.

What you need

• JT308
• PC with USB
• 125KHz RFID cards
• Arduino IDE Software

Steps

1. Download and install Arduino IDE.
2. Connect JT308 to your PC.
3. Check the datasheet for sensor RFID specifications.
4. Create a new project in Arduino IDE.
5. Write the minimum code: `#include `
   void setup() {
   Serial.begin(9600);
   }
   void loop() {
   if (rfid.available()) {
   Serial.println(rfid.readCardSerial());
   }
   }`.
6. Upload the code to your Arduino.
7. Hold an RFID card near the JT308.
8. Check the serial number on the serial console.

Example code

```cpp
#include <RFID.h>

void setup() {
  Serial.begin(9600);
}

void loop() {
  if (rfid.available()) {
    Serial.println(rfid.readCardSerial());
  }
}
```

Mini project

Create a simple access system: read the RFID card and control access to a door.

Common mistakes
