pyAS3992

Provides easy access to AS3992 RFID reader via USB adapter from Python running on Unix machines.

This is a part of a larger project. I published this API since there is no convinient API currently published for communicating with this card, especially not for Python.

Parts I Used

This API was used in order to communicate with the AS3992 UHF RFID reader via UART.

My setup included the following items:

• AS3992 Long Range UHF RFID reader UART (ISO18000-6C EPC G2), purchased here
• SolidDigi Xbee USB Adapter FT232RL chip, purchased here
• Raspberry Pi, running this Python code on Raspbian (This code was only tested on Raspbian and Ubuntu, it probably won't work on a non-Linux OS, since it currently relys on /dev/ttyUSB. It might be useful to change this in the future, but I have no meaning to maintain this)

Connections

Result

Using this API, I was able to sample the AS3992 RFID reader for passive tags nearby.
