Analog Devices / Maxim Integrated DS1925 Thermochron iButton® 温度记录仪
Maxim DS1925 Thermochron iButton® 温度记录仪是坚固耐用的自给系统，能够测量温度并在受保护的内存部分记录测量数据。 以用户定义的速率完成记录。 可以存储 5 分钟至 273 小时范围内等间隔测量的共计 122K 的 8 位读数或 61K 的 16 位读数。 此外，还有 512 字节非易失性内存，用于存储特定应用程序信息。 可以将采集数据的任务编程为立即开始，在用户定义的延迟后开始，或者在温度报警后开始。 可对内存和控制功能的访问设置密码保护。 通过仅需要单一数据引线和接地返回的串行 1-Wire® 协议即可对 DS1925 进行配置并与主机计算设备进行通信。
