Adafruit 10K Precision Epoxy Thermistor [ADA372]

Need to measure something damp? This epoxy-coated precision 1% 10K thermistor is an inexpensive way to measure temperature in weather or liquids. The resistance in 25 °C is 10K (+- 1%). The resistance goes down as it gets warmer and goes up as it gets cooler. For specific temperature-to-resistance, check the lookup table .

These are often used for air conditioners, water lines, and other places where they can get damp. The PVC coating of the wires is good up to 105 °C so this isn't good for very hot stuff.

We even toss in an additional 1% 10K resistor which you can use as calibration or for a resistor divider.

We have a great detailed tutorial on how thermistors work and how to use this one best!
