Detecting temperature changes has never been easier. The MCP9700 is a small thermistor-type temperature sensor. This sensor will output 0.5V at 0 degrees C, 0.75V at 25 C, and 10mV per degree C. Doing an analog-to-digital conversion on the signal line will allow you to establish the local ambient temperature. Detect physical touch based on body heat and ambient conditions with this small sensor.
Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They're even washable!

Thank you for your email, in theory this module can cover between -40 and 125 degrees. This is a thermistor so it basically increases and decreases the resistance of a circuit based on the temperature.
It is intended for use with other micro controller boards like the lily pad main board. These would detect the voltage running through the board. The voltage would increase or decrease depending on temperature. You could then get the controller to trigger out puts based on this.
