Introduction

The DS18B20 is a digital temperature sensor that provides 12-bit Celsius temperature measurements. The DS18B20 communicates over a 1-Wire bus that by design requires only one data line (and ground) for communication with a central microprocessor.

Product Features and Performance

Measures temperatures from -55°C to +125°C (-67°F to +257°F) with ±0.5°C accuracy from -10°C to +85°C

Programmable resolution from 9 to 12 bits

Unique 64-bit serial code for identification

Requires no external components

Measures temperature and outputs a digital signal

Converts temperature to digital word in 750 ms (max.)
