Ano ang THERMISTOR? at paano ito gawing sensor? 

The word “Thermistor” is a combination of the words “Thermally sensitive resistor“. A thermistor is a type of resistor whose resistance changes with the change in temperature. It is a passive component that does not require an extra power source to operate. They are inexpensive and accurate in measuring temperature. But they do not operate well in extreme conditions such as very high or very low temperatures.
The thermistor is used for measuring temperature. The working principle behind the temperature measurement is its resistance.
A thermistor is made of semiconductor material whose resistance greatly depends on the surrounding temperature. They significantly vary with the temperature. Depending on the material used, the resistance may either increase or decrease with an increase in temperature called the PTC and NTC thermistor.
This change in resistance can be calibrated and measured to calculate the exact temperature of the environment in a circuit.
For accurate measurement, It is necessary to have maximum surface contact with the component or equipment. To maximize the thermal conductivity between the surfaces, special thermal paste is used between them.
