Project’s Requirements

Project’s Goals• Designing the system and appropriate packaging, resulting in a

comfortable, friendly, portable and inexpensive modular sensors system device.

• Creating a unique set of software for Smart Phone and the MSSD, which enables creating a database and storing it for the further inspection.

Project’s Basic Concept

MSSD Smart PhoneInterface

User MSSDInterface

User Smart PhoneInterface

Technical Requirements• Wireless portable system worn on the desirable measurement area.• Ability to simply replace different sensors. • Recognition of maximum 3 sensor channels simultaneously.• Alert for ON-OFF mode, “low-battery” state and BT connection

success. • Physical dimensions of the MSSD is small and nonobstructive.• Storing the data describing each measurement in the Smart Phone

memory by BT for performing extended data processing and better tracking.

• Low-power rechargeable battery.
