BiosensorArray - Data Logging

Onboard Storage

Biosensor data stream should be stored in a non-volitile manner on the data aggregator board attached to the body. Ideally, the biosensor array will stream data wirelessly to a smart phone or computer, but this should not be required to ensure operational flexibility. Therefore, a moderate amount of on board storage is required.

EEPROM

• Pro's:
  • Cheaper than flash memory
  • Simpler to interface & manage
    • Drew believes but needs to research

• Con's:
  • Much smaller size that flash memory
  • Not removable

• Implementations:
  • Sparkfun i2c EEPROM chip
  • element14 - Microchip SPI EEPROM

Flash Memory (SD, microSD, etc)

• Pro's:
  • High capacity
  • Removable

• Con's:
  • Higher cost than EEPROM
  • More complex to interface & manange
    • Drew believes but needs to research

• Implementations:
  • Sparkfun - microSD shield
