The DS18B20 digital thermometer provides 9-bit to 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.

2019年7月2日 · 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.

2025年1月28日 · The features and specifications of the DS18B20 temperature sensor include the following. DS18B20 is a digital temperature sensor. This sensor is available in different packages like 8-Pin SO, 8-Pin µSOP & 3-Pin TO-92. Its unique 64-bit address allows multiplexing. It doesn’t need external components.

The digital temperature sensor like DS18B20 follows single wire protocol and it can be used to measure temperature in the range of -67oF to +257oF or -55oC to +125oC with +-5% accuracy. The range of received data from the 1-wire can range from 9-bit to 12-bit.

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

The DS18B20 is a 1-wire programmable Temperature sensor from maxim integrated. It is widely used to measure temperature in hard environments like in chemical solutions, mines or soil etc.

It has an operating temperature range of -55°C to +125°C and is accurate to ±0.5°C over the range of -10°C to +85°C. In addition, the DS18B20 can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply.
