13 vary in resistance in an often non-linear way in relation to temperature.
14 The negative temperature coefficient means that the resistance decreases
15 as the temperature rises. Since the relationship between resistance and
16 temperature is non-linear, software drivers most often need to use a look
17 up table and interpolation to get from resistance to temperature.
