理想中的智能家居环境可能是这样的:智能手机可以控制家里的门窗、视频监控、智能插座、智能照明系统以及室温、环境监测等, 物联网WiFi模块在智能家居应用中占有一定优势。

物联网应用中无线连接技术是最关键的,目前已经有基于WiFi模块、蓝牙模块的物联网应用方案。那么问题来了,智能家居中的物联网WiFi模块选型有哪些注意点呢?

WiFi模块属于物联网传输层,IOT串口WiFi是基于Uart接口的符合wifi无线网络标准的嵌入式模块,内置无线网络协议IEEE802.11b.g.n协议栈以及TCP/IP协议栈,可将串口或TTL电平转为符合WiFi无线网络通信标准的嵌入式模块。

智能家居的一个重点便是联网,因此用于智能家居的无线系统需要满足几个特性:低功耗、稳定、易于扩展并网。WiFi模块是一种短程无线传输技术,能够在数百米范围内支持互联网接入的无线电信号。它的最大特点就是方便人们随时随地接入互联网。

WiFi技术在智能家居中的应用的主要优点有:

WiFi智能节点可以直接连接无线路由器,从而接入Internet网;不需要家庭网关,节点可以任意扩充;不会破坏现有装修;智能手机可以进行局域网控制和远程控制。

目前市场上出现多款物联网WiFi无线通信模块,其中IoT ESP8266 WiFi模块: PWF-ESP8266-501MFPWF-ESP8266-301M,可将用户的物理设备连接到WiFi无线网络上,进行互联网或是局域网通信,实现联网功能。一般可用作IoT WiFi模块, 智能家居WiFi模块, 智能语音WiFi模块,iftttWiFi模块, google assistantWiFi模块, 谷歌语音助手WiFi模块,亚马逊WiFi模块, 智能音箱WiFi模块, echo语音控制WiFi模块。

IOT WiFi模块:模块内部集成了射频收发、MAC、基带处理、WiFi协议和配置信息及网络协议栈,用户利用它可以轻松实现串口设备的无线网络功能,节省开发时间,使产品更快地投入市场,增强竞争力。

基于迅准科技IoT ESP8266 5V WiFi模块的智能家居解决方案:

PWF-ESP8266-501M是一款基于ESP8266的低成本、高集成度的串口WiFi模块,支持IEEE802.11b/g/n 1T1R完整的 TCP/IP 协议栈。用户可以使用该模块为现有的设备添加联网功能,也可以构建独立的网络控制器。
