By measuring the resistance value change of the thermistor, the temperature can be determined.

From the magnitude of the thermoelectric potential, the temperature can be determined. The operating principle of thermocouples is based on the measurement of thermoelectric effects and thermoelectric voltages.
The working principle of the thermal resistor is that the resistance value can change along with the temperature, wherein the resistance value of the NTC resistor can be reduced when the temperature is increased; the PTC resistor increases in resistance as the temperature increases. The thermal resistor is connected to a circuit that provides a known current or voltage supply.

Different types of magnetoresistive sensors include magnetoresistive strips (AMR), giant Magnetoresistance (GMR), tunneling Magnetoresistance (TMR), and the like. These sensors measure magnetic field strength using the property of the material's resistance value as a function of external magnetic field
