CC2530就是给物联网设计的芯片,功耗极低,价格也相对低,关于物联网开发的资料是相对要多的
个人推荐是用CC2530与LoRa相比,在同样灵敏度的情况下,采用该技术的ZETA模组通信速率可达LoRa的3倍,而在同样的速率下,极限接收灵敏度还比LoRa优53dB。也就是说,同样条件下,ZETA传感器可以听到比LoRa低 53分贝的声音,而如同在相同声音条件下,可以达到3倍的传输带宽。在该技术的应用之下,ZETA在低于120km/h时速的移动场景里也可以应用,典型传输距离可达3-5km。Most of us use computers to search for more information about the interesting problems on the textbooks,about Iraqi wars and about OscarSome of us use computers to do some drawings,to make up interesting flashesAnd some of us use them to play gamesIf we are tired and want to take a short rest,playing games for a while is OKBut it’s forbidden that we spend hours and hours on the gamesThere is also someone using computers to talk with people in the Internet and even falling in love with him or herThe Internet is not a real world and we can’t tell lies from truths区别:
1、无线的安装部署简单,有线安装部署实施代价高;
2、无线的覆盖范围相对广,部署成本相对低,有线则相反;
建议:
1、可以采取局部有线+整体无线的部署方式,性价比最优。
如,在终端设备端(如传感设备)用有线连接集中器(类似电力抄表的方案),然后集中器通过无线跟后台服务器连接。
