5 Minutes! Understand NTC Thermistors!
An NTC thermistor is a simple temperature sensor that is widely used in consumer electronics. It is a typical semiconductor resistor whose resistance decreases gradually as temperature rises. NTC thermistors are primarily manufactured from metal oxides such as manganese, cobalt, nickel, and copper using ceramic processing techniques.

Some key points about the DS18B20 digital temperature sensor
The DS18B20 digital temperature sensor converts one form of energy into another. There are two types of conversion: active and passive. An active sensor can directly convert one form of energy into another without requiring an external power supply or excitation source. A passive sensor cannot directly convert energy forms but can modulate the energy or excitation supplied from another input. The sensor’s role is to transduce specific characteristics of an object or process into a measurable quantity.

Main features of the PT100 temperature probe
If you need to measure and control temperatures between 70 K and 500 K, PT100 platinum resistance thermometers are an excellent choice. Within this temperature range, they offer outstanding repeatability and nearly constant sensitivity. Within the specified accuracy limits (±1°C), PT100 temperature probes can also be used in magnetic fields and under radiation exposure.
