The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. In addition, the DS18B20 can derive power directly from the data line ("parasite power"), eliminating the need for …

12-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor.

Learn how to use DS18B20 1-Wire digital temperature sensors with Arduino. Wiring diagrams and many example codes included!

Jul 2, 2019 · The DS18B20 temperature sensor is a One-Wire digital temperature sensor. Learn how to read the temperature from one or multiple DS18B20 sensors with an Arduino.

The DS18B20 Digital Thermometer provides 9 to 12-bit (configurable) temperature readings which indicate the temperature of the device. Information is sent to/from the DS18B20 over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor to a DS18B20. Power for reading, writing, and

DS18B20+ – Temperature Sensor Digital, Local -55°C ~ 125°C 12 b TO-92-3 from Analog Devices Inc./Maxim Integrated. Pricing and Availability on millions of electronic components from Digi-Key Electronics.

The DS18B20 is a 1-Wire® temperature sensor manufactured by Dallas Semiconductor (acquired by Maxim Integrated). Because it is a 1-wire device, it only needs one digital pin to communicate with the microcontroller.
