节点介绍--Moteiv <wbr>Tmote <wbr>Sky!!

    这就是本世纪3大信息技术之一的无线传感器网络技术中用到的节点,最开始称为智能尘埃,由美国军方牵头研究,现在已经成为当前的研究热点。将来的一大用途是用于无人职守的恶劣环境中,以自组织的网络工作。例如,在战争状态中,将其大面积撒入到敌方的阵地,这些节点将会自组织成网络,迅速得到敌方地形,再把地形数据通过网络传输回我方阵地。

    Reliable low-power wireless sensor networking eases delopment and deployment.

    Tmote Sky is the next-generation mote platform for extremely low power, high data-rate, sensor network applications designed with the dual goal of fault tolerance and development ease. Tmote Sky boasts the largest on-chip RAM size (10kB) of any mote, the first IEEE 802.15.4 radio, and an integrated on-board antenna providing up to 125 meter range. Toward development ease, Tmote Sky provides an easy-to-use USB protocol for programming, debugging and data collection.

    Tmote Sky offers a number of integrated peripherals including a 12-bit ADC and DAC, Timer, I2C, SPI, and UART bus protocols, and a performance boosting DMA controller. Tmote Sky offers a robust solution with hardware protected external flash (1Mb in size), applications may be wirelessly programmed to the Tmote Sky module. In the event of a malfunctioning program, the module loads a protected image from flash.

     Designed with applications in mind, the Tmote Sky module has received FCC certification and may be added into existing products.

     With TinyOS support out-of-the-box, Tmote Sky leverages emerging wireless protocols and the open source software movement. Tmote Sky is part of a line of modules featuring optional on-board sensors to increase robustness while decreasing cost and package size.

     Tmote Sky is functionally equivalent to Moteiv's Telos Revision B. All Telos Revision B code will run without modifications on the Tmote Sky module.
