Project Description Short range wireless control device Project Client is Honeywell Contact: Justin Young Four deliverables Transmitter, Receiver, Programming Dongle, and GUI Desired outcome of this project is for the transmitter to communicate with receiver and have the receiver perform a particular command that was programmed via the wireless dongle. 3

Design Overview System consists of four components: Transmitter(Tx) Receiver(Rx) Bluetooth Dongle GUI for programming Rx 4

Functional Requirements Minimum distance of 50ft between Rx and Tx Minimum distance of 5ft between programming dongle and Rx ● Receiver shall have 2 LEDs ● Tx and Rx battery life should last at least 8 hours ● Minimum distance of 25ft for talk back from Rx 5

Non-Functional Requirements ● Tx and Rx housing less than 1" X 1.5" X 2.5" ● Tx and Rx should withstand rain and drop ● Temperature range -25°F to 160°F ● Tx and Rx should have a self contained power source ● Rx antenna should be internal 6

Stretch Goals ● Minimum distance of 100ft between Rx and Tx ● Tx and Rx housing less than.5" X 1" X 2" ● Easy access to Tx and Rx power supplies ● Tx antenna should be internal ● Tx and Rx battery life should last at least 24 hrs. ● Full talk back from Rx up to a distance of 100ft 7
