How the temperature sensor works

Temperature sensors use various principles to measure temperature and convert it into an electrical signal. How they work includes: Thermocouples utilize the thermal electromotive force between dissimilar metals; RTDs measure resistance as a function of temperature; NTC/PTC thermistors change semiconductor resistance; Temperature diodes have a forward bias voltage proportional to temperature; Infrared sensors detect Infrared radiation from a target object; silicon sensors convert temperature using analog or digital technology.
