RFID poc

Description

This is a sample script reading the input from an USB RFID reader connected to a Raspberry Pi to trigger on/off commands controlling a LED light bulb.

The RFID used is a RFIDeas pcProx 125 kHz which basically simulates keyboard input.

The python script uses evdev to read the input and make a POST request to a controller server that manages the light bulbs.

Documentation

Once you plug the RFID reader to the Pi's USB, if you run the lsusb command it should be listed there:

Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. 
Bus 001 Device 004: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter
Bus 001 Device 005: ID 0c27:3bfa RFIDeas, Inc pcProx Card Reader

Once your device is recognized, you can run the script:

$ sudo python rfid_light.py -o 2714

The -o option is the RFID card number that will be used to trigger the on command. Any other value will trigger the off command. Simple as that.
