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

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

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

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.

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
