An RTD (Resistance Temperature Detector) is a sensor whose resistance changes as its temperature changes. The resistance increases as the temperature of the sensor increases.

The RTD wire is typically platinum (Pt), nickel (Ni), or copper (Cu). The material has an accurate temperature–resistance relationship which is used to provide an indication of temperature.
