To the ceramic he’s fitted a thermistor, which sits in the gate bias circuit of a MOSFET. The MOSFET in turn operates a relay which supplies mains power to the iron. Temperature regulation comes ...

Finally, you will take a deep dive into interfacing a thermistor and associated front end components ... In module 4 you will learn the theory and practical application of amplifiers and circuit noise ...

This transistor switching circuit uses an npn transistor, a voltage divider (consisting of a \(5 kΩ \) resistor and thermistor) and a \(5 V\) power supply. Use the information in the table to ...

Of course, the standard way of controlling CPU fans these days is with PWM, so he built a circuit which essentially converts the PWM signal from the motherboard into a phantom thermistor.
