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: [[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: [[2]]
- 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.
- Advantages
Status
- Communications testing complete - 4/10/2011 [[3]]
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
