DSl820数字温度计提供9位(二进制)温度读数指示器件的温度信息经过单线接口送
入DSl820或从DSl820送出因此从主机CPU到DSl820仅需一条线(和地线)DSl820的电源可以由数据线本身提供而不需要外部电源因为每一个DSl820在出厂时已经给定了唯一的序号因此任意多个DSl820可以存放在同一条单线总线上这允许在许多不同的地方放置温度敏感器件DSl820的测量范围从-55到+125增量值为0.5可在l s(典型值)内把温度变换成数字-DSl820 digital thermometer provides 9-bit (binary) temperature readings indicative of the temperature device information through one-way interface into DSl820 or from DSl820 sent from the host CPU to DSl820 just a line (and ground) DSl820 power can be provided by the data line itself without the need for external power supply because each DSl820 at the factory have been given a unique serial number so any number can be stored in DSl820 with a single bus which allows many different places in the temperature-sensitive device placed DSl820 measuring range-55 to+125 from the incremental value of 0.5 in the ls (typical value) within the temperature transform into digital
