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

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.

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.

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

2025年1月28日 · DS18B20 digital temperature sensor provides temperature measurements that range from 9-bit to 12-bit Celsius. Thus this sensor can also have an alarm function including nonvolatile user-programmable lower and upper trigger points.
