2. Project Description Short range wireless control device
Honeywell is client
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 do a particular command that was programmed by the wireless dongle.

5. Rx Block Diagram

6. Functional Requirements
Minimum 50ft between Rx and Tx
Minimum 5ft between programming dongle and Rx
Receiver shall have 2 LEDs
Tx and Rx battery life should last at least 8 hrs.
Minimum 25ft talk back from Rx

7. Non-Functional Requirements
Tx and Rx less than 1" X 1.5" X 2.5"
Tx and Rx should withstand rain and drop
Temperature range -25F to 160F (-31.67C to 71.11C)
Tx and Rx should have a self contained power source
Rx shall not have external antenna

8. Stretch Goals Minimum 100ft between Rx and Tx
Tx and Rx less than .5" X 1" X 2"
Easy access to Tx and Rx power
Tx shall not have external antenna
Tx and Rx battery life should last at least 24 hrs.
Full talk back from Rx

9. Constraints and Technology Considerations
Transmission distance
Long Battery life
User friendly interface
Size – device must fit in small housing
(less than 1" X 1.5" X 2.5")
Environment
-25F to 160F
Withstand rain and drop from 3ft.

10. Risks and Mitigation Limited knowledge of Bluetooth technology
Limited experience with PCB design
Limited knowledge of programing of microcontrollers
Will work with Honeywell and Dr. Wang for help with many issues that we may encounter
