The MCP9700 is a small thermistor-type temperature sensor. This sensor will output 0.5V at 0 °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.
Add this to your LilyPad wearable Arduino system to detect physical touch based on body heat, or ambient conditions.
LilyPad Overview LilyPad is a wearable e-textile technology developed by Leah Buechley. Each LilyPad is designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. Most are even washable — just remember to remove any batteries first.
See our LilyPad category to find more LilyPad components and conductive thread you can use to sew a circuit into clothing.
