## Temperature sensors types {#temperature-sensors-types}

There are three main types of temperature sensors:

-   [RTD](#org-target--sec-temperature-sensor-rtd) (Resistance Temperature Detectors): made of pure metals (Pt, Ni or Cu)
    They are all PTC (Positive Temperature Coefficient): PT100, PT1000, ...
-   [Thermistor](#org-target--sec-temperature-sensor-thermistor): made of metal oxide mixtures (semiconductor materials).
    It can have a NTC (Negative Temperature Coefficient) or a PTC (Positive Temperature Coefficient).
-   [Thermocouple](#org-target--sec-temperature-sensor-thermocouple) (Seebeck effect):
    -   Type K (-180 to 1200 degC)
    -   Type T (-250 to 350 degC)
