Thermistors are a simple but very precise method of measuring temperature. The resistance changes dramatically as the body gets colder and hotter. Thermistors tend not to be used for very hot temperatures (these low cost ones have vinyl wires that top out at 100c degrees C) but they’re much cheaper than thermocouples and very easy to read using a simple voltage divider. They’re more precise than digital temperature sensors (those always have an error of +-1 degree C) at 1% you can get better than +-0.2 degree C. These are often used for cold/warm temperature sensing and for battery chargers.
We carry a basic 10K 1% NTC thermistor but you can also pick up a range at digikey.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

I think you must mean 105c or something close.
woops, typo fixed. 105C is correct, but we suggest no more than 100C anyways 🙂
Arenasolutions PartSaver will be a good companion to the Part Finder. Once you identify a part you want to use, click a button in the browser it will add an entry for the part in your spreadsheet in Google Docs. Would love to hear from you about the utility of the PartSaver and any other feedback you may have. There is a feedback button in PartSaver interface.
