1 RFID Pet Door Andrew Parr Conner Rocole Ben Peetz Eric Sturm EE 494, Fall 2006

2 Introduction To design and build an automated system to regulate and monitor a pet’s movement into and out off a structure with minimal human intervention.

3 Requirements Reliability Reliability Simple User Interface Simple User Interface Safe for the Pet Safe for the Pet Scalable Scalable

4 Implementation 1.Run Locked Enter Only Exit Only Enter or Exit 2.Manual 3.Program An RFID tag attached to a pet’s collar will be read by a scanner when the pet is in the proximity of the door. If the scanned pet has been programmed by the user to have access to the door, the Pet Door will then unlock. This will allow the pet to open the door and pass through it. Once the door returns to a rest position, the door will be locked until another approved pet is scanned. The system will operate in three basic modes.
