ADDSMART is a research project focused on digitizing addresses of locations and building a smart mailbox by combining wireless sensors, cameras, locks, and RFID readers and tags into a system controlled by an Arduino microcontroller board. We explored the idea of address digitization (using RFID tags to store addresses) and incorporated it into a mailbox that can communicate wirelessly with the homeowner to provide mail status updates and home security footage through digital photographs. This paper demonstrates our proposed ideas, describes the design of a smart mailbox, the technology we have used to build a prototype, and the current results of work along with future research ideas.
