TinyOS是UC Berkeley（加州大学伯克利分校）开发的开放源代码操作系统，专为嵌入式无线传感网络设计，操作系统基于构件（component-based）的架构使得快速的更新成为可能，而这又减小了受传感网络存储器限制的代码长度。

　TinyOS目前的最新版本为TinyOS 2.1

-TinyOS is a UC Berkeley (University of California, Berkeley) development of the open-source operating system, designed for embedded wireless sensor network design, operating systems, component-based (component-based) architecture makes it possible to quickly update, which in turn reduced smaller by the sensing network storage limit code size. TinyOS is currently the latest version of TinyOS 2.1
