How to Interface NTC Thermistor with PIC18F4550
Overview of NTC Thermistor A thermistor is a type of variable resistor whose resistance changes with temperature. For PTC (Positive Temperature Coefficient) thermistors, the resistance increases as the temperature rises. In contrast, for NTC (Negative Temperature Coefficient) thermistors, the resistance decreases as the temperature increases. Thermistors are commonly used in applications such as current limiting, …
