Product Description：
DS18B20 is a commonly used digital temperature sensor. It is a single-bus digital temperature sensor produced by DALLAS Company. It adopts a unique single-wire interface mode, and only one data line is required to achieve two-way communication with the microprocessor. Its operating temperature range is from -55°C to +125°C. In the range from -10°C to +85°C, the measurement accuracy can reach ±0.5°C. It can directly convert the temperature signal into a digital signal for output, making it convenient for the microprocessor to process and control.
Product Features:
Single-bus interface: Only one signal line is needed to connect with the microcontroller. The wiring is simple, which can greatly save the I/O pin resources of the microcontroller. And it is convenient to build a multi-point temperature measurement network. Multiple DS18B20 sensors can be connected to the same bus.
Digital output: It directly outputs digital quantities without the need for an external analog-to-digital conversion circuit, reducing interference during signal transmission and improving the accuracy and stability of measurement.
High temperature measurement accuracy: It can maintain high measurement accuracy within a wide temperature range, meeting the requirements of many occasions with high requirements for temperature measurement accuracy.
Networkable: Multiple DS18B20s can be connected in parallel on the only single bus to achieve multi-point temperature measurement, making it suitable for large-scale temperature monitoring systems.
No external power supply required: It can be powered by a parasitic power supply method, that is, it directly obtains power from the data line without the need for an additional power line, further simplifying the circuit design.
DS18B20 are used in a wide variety of applications:
Industrial temperature detection: It is suitable for temperature monitoring and control in industrial production processes, such as temperature monitoring of chemical reaction kettles, temperature control of metal heat treatment, etc., which helps to ensure the stability of the production process and product quality.
Environmental temperature monitoring: It can be applied to scenarios such as meteorological observation, warehouse environmental monitoring, and computer room temperature monitoring, to grasp the environmental temperature changes in real time and provide a basis for environmental adjustment and equipment protection.
Smart home: In household appliances such as air conditioners, refrigerators, and underfloor heating, it is used for accurate temperature measurement and control to achieve a comfortable home environment and energy-saving effects.
Medical equipment: In medical equipment such as medical incubators, refrigerators, and body temperature measuring instruments, DS18B20 can provide accurate temperature measurement to ensure the safety and reliability of the medical process.
