The goal of this sensor is to provide regular measurement of the user's core body temperature.
+
+
===Version 1.0===
+
+
==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: [[http://www.sparkfun.com/products/9418]]
+
**'''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
