What type of sensor measures temperature?

The type of sensor that measures temperature includes a thermocouple or thermistor.

A thermocouple consists of two different metals joined together at one end, and when the junction experiences a change in temperature, it produces a voltage that can be correlated to temperature changes. This makes thermocouples versatile and commonly used in various applications, from industrial to household thermometers.

On the other hand, a thermistor is a type of resistor whose resistance varies significantly with temperature changes. Thermistors are usually made of ceramic materials and are very sensitive, making them ideal for precise temperature measurement in various applications, such as in HVAC systems, automotive sensors, and consumer electronics.

Both of these sensors are widely recognized and used for their effectiveness and reliability in measuring temperature across numerous settings. This unique capability distinguishes them from the other options listed, which are intended for different measurement purposes.
