Thermistors

Please peruse Circuit Specialists' lineup of low-cost negative temperature coefficient (NTC) thermistors — a portmanteau of "thermal" and "resistor" — which raise the temperature of a semiconductor to increase the number of electrons available to move and carry charge, thus elevating them into the conduction band; the more charge carriers available, the more current conducted. We also carry NTC thermistor kits which contain sixty thermistors of varying values.
