|
The ``pn532`` binary sensor platform lets you track if an NFC/RFID tag with a given
|
|
unique id (``uid``) is currently being detected by the PN532 or not.

Configuration variables:
|
|
------------------------
|
|
|
|
- **uid** (**Required**, string): The unique ID of the NFC/RFID tag. This is a hyphen-separated list
|
|
of hexadecimal values. For example ``74-10-37-94``.
|
|
- **name** (**Required**, string): The name of the binary sensor.
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
- All other options from :ref:`Binary Sensor <config-binary_sensor>` and :ref:`MQTT Component <config-mqtt-component>`.

Setting Up Tags
|
|
---------------
|
|
|
|
To set up binary sensors for specific NFC tags you first have to know their unique IDs. To obtain this
|
|
id, first set up a simple pn532 configuration without any binary sensors like above.
|
|
|
|
When your code is running and you approach the PN532 with an NFC Tag, you should see a message like this:
|
|
|
|
.. code::
|
|
|
|
Found new tag '74-10-37-94'
|
|
|
|
Then copy this id and create a ``binary_sensor`` entry as in the configuration example. Repeat this process for
|
|
each tag.
