Working Principle

An NTC thermistor operates by changing its electrical resistance according to temperature. When the surrounding temperature increases, the resistance of the thermistor decreases. A microcontroller or electronic circuit measures this resistance variation and converts it into a corresponding temperature value using calibration data or mathematical calculations. This enables accurate temperature monitoring, thermal protection, and automatic temperature control in electronic systems.
