LilyPad Temperature Sensor

The LilyPad Temperature Sensor is a compact and versatile tool for detecting temperature changes. It is based on the MCP9700, a small thermistor type temperature sensor. The sensor outputs 0.5V at 0 degrees Celsius, 0.75V at 25 degrees Celsius, and 10mV per degree Celsius. By performing an analog to digital conversion on the signal line, you can determine the local ambient temperature. This feature also allows the sensor to detect physical touch based on body heat and ambient conditions.

The LilyPad Temperature Sensor is part of the LilyPad wearable e-textile technology, a brainchild of Leah Buechley, developed in cooperation with SparkFun. Each LilyPad is ingeniously designed with large connection pads, enabling them to be sewn into clothing. A variety of input, output, power, and sensor boards are available, and they are all washable! This makes the LilyPad Temperature Sensor ideal for interactive clothing and wearable tech projects.

Every purchase of the LilyPad Temperature Sensor supports Dr. Leah Buechley's ongoing work in the development and education of e-textiles. This is a great way to contribute to the future of wearable technology while benefiting from its current innovations.

The LilyPad Temperature Sensor is 20mm in outer diameter and features a thin 2.032mm PCB. This makes it lightweight and easy to incorporate into any clothing or fabric. It is a reliable, user-friendly tool for all your temperature sensing needs in wearable tech.

Supporting documents for the LilyPad Temperature Sensor are available, including a schematic, Eagle files, a hookup guide, a datasheet for the MCP9700, and design files on GitHub. These resources make it easy to get started and maximize the use of the LilyPad Temperature Sensor.
