What is the working process of the DS18B20 temperature sensor?The read/write sequence and temperature measurement principle of the DS18B20 temperature sensor are the same as the DS1820, but the number of digits of the obtained temperature value is different due to different resolutions.

What is the significance of the DS18B20 temperature sensor?The DS18B20 temperature sensor is waterproof so that the sensor can be completely immersed in liquid.

Temperature sensing can be of two types: contact and non-contact. In contact-based temperature sensing, the sensor will be in physical contact with the object being sensed. In non-contact temperature sensing, the sensor interprets the radiant energy of the heat source. Radiant energy is the form of energy emitted in the infrared portion of the electromagnetic spectrum. Non-reflective solids and liquids can be monitored using non-contact techniques.

A temperature sensor is a sensor that detects the temperature and converts it into a usable output signal. The temperature sensor is the heart of the temperature meter and there are many variants. Depending on the measurement method, it can be divided into two categories: contact type and non-contact type. According to the properties of sensor materials and electronic components, it can be divided into two categories: thermal resistance and thermocouple.

The thermal resistance temperature sensor is a sensor thermometer that uses the principle that the resistance value of a conductor or semiconductor changes with temperature.
