This is a Raspberry Pi RFID HAT Module operating in the 125Khz frequency range. It supports two communication interfacs: UART for RFID and I2C for Oled Display.
- Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
- Two interface options: UART for RFID, I2C for Oled Display
- User configurable buzzer (connected on GPIO 17 of Raspberry pi)
- Attendance_system : A GUI based attendance system using our rfid hat and rfid tags/cards.
- Lock_Pi : You can use this project to log-ff raspberry pi using this rfid hat. To login you have to manually type password to log on again.
I2C/Serial interface is disabled by default in Raspberry Pi, To enable it type below command.
sudo raspi-config
- Now select Interfacing options.
- Now we need to select I2C option.
- Now select Yes and press enter and then ok.
To enable serial,
- select interfacing options.
- Now we need to select serial.
- select no to disable serial over login shell.
- Now select yes to enable serial hardware port then ok.
After this step reboot raspberry by typing below command:
sudo reboot
- sudo apt-get install python-smbus
- sudo apt-get install i2c-tools
To verify the list of connected device on I2C interface, you can run below commond :
sudo i2cdetect -y 1
To run examples of SB-PI-HAT, clone this repository by executing below command
git clone https://github.com/sbcshop/SB-RFID-HAT.git
cd SB-RFID-HAT
python3 rfid.py (Without Oled display, output on terminal/shell)
OR
python3 rfid_with_oled.py ( To show detected tag id on Oled as well as on terminal/shell)
