Biosensor Array Body Temperature

The goal of this sensor is to provide regular measurement of the user's core body temperature.

Sensor Specifications

• It has been decided to locate the sensor in the armpit of the user as placing it in the mouth presents a choking hazard during physical activities.
• The sensor chosen is the TMP102 breakout board available from Sparkfun Electronics: [[1]]
  • Advantages
    • Digital I/O means we can use flexible wires as opposed to more brittle thermocouple wire that can break if kinked.
    • Sparkfun provides a link to pre-existing Arduino code for this sensor hosted on the Wiring website: http://wiring.org.co/learning/libraries/tmp102sparkfun.html
    • Small enough to fit under a person's armpit
    • Reasonably fast response rate.
  • Disadvantages
    • Bare PCB requires some kind of enclosure or other potection from sweat and other moisture.

Status

• Communications testing complete - 4/10/2011

To Be Completed

• Selection of rugged multi-conductor data/power cable.
  • Four conductors needed
• Selection of strain relief
• Selection of plug type for connecting to the on-body base unit
  • BNC?
• Design and fabrication of sensor enclosure.
  • 3/4" NPT Aluminum pipe fitting cap and 3/4" NPT Aluminum pipe fitting plug
