一、DS18B20 的主要特性
(1)适应电压范围更宽,电压范围:3.0~5.5V,在寄生电源方式下可由数据线供电
(2)独特的单线接口方式,DS18B20 在与微处理器连接时仅需要一条口线即可实现微处理器与
DS18B20 的双向通讯
(3)DS18B20 支持多点组网功能,多个 DS18B20 可以并联在唯一的三线上,实现组网多点测温-FEATURES
Unique 1-Wire
®
interface requires only one
port pin for communication
Provides unique 64-bit serial number to
battery packs
Eliminates thermistors by sensing battery
temperature on-chip
On-board A/D converter allows monitoring
of battery voltage for end-of-charge and end-of-discharge determination
On-board integrated current accumulator
facilitates fuel gauging
Elapsed time meter in binary format
