While that’s true of all resistors, with thermistors the change is larger and desired. They come in two types: NTC, or Negative Temperature Coefficient thermistors, where as the temperature ...
A thermistor is a device that’s resistance changes with temperature. The resistance of an NTC thermistor decreases with increasing temperature. A voltage-current graph for a thermistor is shown ...
After taking the Aeroccino apart and going over the circuit, it seemed like a simple design relying on a resistor and NTC (negative temperature coefficient) thermistor connected to an ATTiny44 ...
