無線傳感器部署的連接性結(jié)構(gòu)和協(xié)議選項(xiàng)

　　隨著越來越多的人接受基于云的連接的基礎(chǔ)設(shè)施監(jiān)控和控制的概念，芯片和模塊制造商正在加緊板引入點(diǎn)至點(diǎn)，聚合和網(wǎng)狀網(wǎng)絡(luò)連接的分布式傳感器和遠(yuǎn)程訪問。

　　這些高層次的積木讓工程師和公司創(chuàng)造和引進(jìn)產(chǎn)品的速度比以往任何時(shí)候都快。不再需要研究和學(xué)習(xí)錯(cuò)綜復(fù)雜的幾個(gè)100頁加上網(wǎng)絡(luò)拓?fù)湟?guī)范。不再需要重復(fù)PCB布局和調(diào)整組件值，找到正確的組合，最大限度地提高性能，同時(shí)最大限度地減少空間，功耗和成本。

　　What’s more， there is a closely knit relationship between finished OEM and eval modules/kits that let you reference a pre-developed design， modify it， experiment a bit， and reproduce the results in your constrained system. In most cases， source code for the communications and protocol stacks are available （usually under NDA） so you can modify the native functionality of an OEM device， and， often， share the same processor.

　　This article looks at several new entries in the wireless sensor arena as well as the development kits and demo units that support them. It discusses some of the choices we can make concerning connectivity architectures and protocols， and examines the pros and cons of each solution. All parts， data sheets， tutorials， and development systems referenced here can be found on the Digi-Key website.
