Sensitive resistor will change with changes in physical

Sensitive Resistor: refers to the resistance value of a physical quantity (such as temperature, humidity, light, voltage, mechanical force, and the gas concentration, etc.) has a sensitivity feature, when these quantities change, will be sensitive resistor with altered by physical changes, showing electric transformer values​​. According to the different quantities sensitive, sensitive resistors can be divided into thermal, humidity, light-sensitive, sensitive, force-sensitive, magnetic and other types of gas-sensitive resistors. Sensitive resistors are used in almost all electric meter, such resistors is also known as a semiconductor resistor.
Thermistor resistance varies with temperature, temperature resistance for the negative temperature coefficient (NTC) thermistor. Application of more negative temperature coefficient thermistor, can be divided into common type negative temperature coefficient thermistor; regulator type negative air circuit breaker thermistor; temperature type negative temperature coefficient thermistor. Photoresistor is a resistor changes with the intensity of the incident light to change, when the incident light into the resistor enhancement, photosensitive resistance decreases, the resistance increases when the incident light is attenuated.
