无线传感器部署的连接性结构和协议选项

　　无线传感器部署的连接性结构和协议选项

　　随着越来越多的人接受基于云的连接的基础设施监控和控制的概念，芯片和模块制造商正在加紧板引入点至点，聚合和网状网络连接的分布式传感器和远程访问。

　　这些高层次的积木让工程师和公司创造和引进产品的速度比以往任何时候都快。不再需要研究和学习错综复杂的几个100页加上网络拓扑规范。不再需要重复PCB布局和调整组件值，找到正确的组合，最大限度地提高性能，同时最大限度地减少空间，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.
