I don't have one, but assuming they measure temperature, I would expect that it's a common, cheap thermistor, 10K ones are commonly used, but they could be of other values or type.

differ from resistance temperature detectors (RTDs) in that the material used in a thermistor is generally a ceramic or polymer, while RTDs use pure metals.

The RTD wire is a pure material, typically platinum, nickel, or copper. The material has an accurate resistance/temperature relationship which is used to provide an indication of temperature.
