* 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.
