The DS18B20 is a popular digital temperature sensor with the features of small size, minimal hardware overhead, strong anti-interference capabilities, and high precision. It outputs digital signals. The DS18B20 digital temperature sensor is simple to wire and is packaged in a variety of ways, including pipeline, screw, magnet adsorption, stainless steel, and numerous model options.
The temperature coefficient of resistance for NTC (negative temperature coefficient) thermistors is in the range of -2%/k to -6%/k, which is approximately metal 10 times the temperature coefficient of resistance. They are heat-sensitive semiconductor resistors whose resistance value decreases with increasing temperature. The NTC thermistor's resistance value may change due to changes in the temperature of the surrounding environment or because of current flow and self-heating. His many applications are based on this trait. NTC thermistors are made of mixed oxide polycrystalline ceramics. This material's conduction process is highly intricate.
