DS18B20

1. 說明

用於1線網絡測溫系統進行測溫。

探頭長度:1 m

內置芯片:DS18B20

新型“一線器件”BS18B20體積更小,適用電壓更寬,更經濟。

Dallas Semiconductor’s digital temperature sensor DS1820 supports temperature sensing of the “first-line bus” interface Machine. The unique and economical characteristics of the first-line bus make it easy for users to form sensor networks and introduce a new concept for the construction of measurement systems.

Now, the new generation of “DS18B20” is smaller, more economical, and more flexible. This allows you to give full play to the strengths of the “first-line bus.”

The following is a detailed application of DS1820.
