RFID Reader

To assist in tracking animal behaviour, particularly when multiple animals are present in the habitat, unique RFID emitters can be attached or implanted subcutaneously to individual animals, and Harp RFID reader devices placed at key points of the habitat (e.g. entry and exit points, close to a foraging patch).

Nodes

RfidReader

The RfidReader (Aeon.Environment) node establishes a connection to an RFID reader and shares events generated by RFID proximity to shared Subjects, reporting which animal is near which location.

Inputs

None

Outputs

Stream of all events emitted by the Harp RFID reader device

Properties

General

Property name	Description
HardwareNotificationsState	Enables or disables hardware notifications
Location	The location, in pixel space, with which to associate detection events
PortName	The COM port the physical RFID reader is connected to

Subjects

Events from the RFID reader are published to Subjects. Here you set the names used for these Subjects to identify events, commands or data streams for this node for a specific RFID reader. Each of these subjects becomes accessible in the Bonsai editor’s toolbox anywhere in the workflow using the name set here.

Usage

Create a GroupWorkflow node and give it an appropriate name, e.g. “Patch1Rfid”. Inside, place an RFIDReader (Aeon.Environment) node, externalise all properties, and connect it to the WorkflowOutput.
