10K Ohm NTC Thermistor Temperature Sensor

10K Ohm NTC Thermistor Temperature Sensor

The 10K Ohm NTC (Negative Temperature Coefficient) Thermistor is a temperature-sensitive resistor whose resistance decreases as temperature increases. It is widely used for accurate temperature measurement, monitoring, and control applications due to its fast response, compact size, and low cost.

Working Principle

The thermistor operates on the negative temperature coefficient principle. At lower temperatures, the resistance of the thermistor is high. As temperature rises, the semiconductor material inside the thermistor allows more charge carriers to flow, reducing resistance. This resistance change is converted into a voltage signal using a voltage divider circuit and read by a microcontroller or analog system.
