termistores
A thermistor is a type of resistor whose resistance is strongly dependent on temperature, more so than in standard resistors. The word "thermistor" is a portmanteau of "thermal" and "resistor". Thermistors are widely used as temperature sensors. The two types of thermistors are NTC (Negative Temperature Coefficient) and PTC (Positive Temperature Coefficient).
In an NTC thermistor, the resistance decreases as temperature increases. This is due to the presence of
In a PTC thermistor, the resistance increases as temperature increases. These are often made from ceramic materials.
The primary advantage of thermistors is their high sensitivity to temperature changes, allowing for precise measurements.
