  Wi-Fi模块又名串口Wi-Fi模块,属于物联网传输层,功能是将串口或TTL电平转为符合Wi-Fi无线网络通信标准的嵌入式模块,内置无线网络协议IEEE802.11b.g.n协议栈以及TCP/IP协议栈。传统的硬件设备嵌入Wi-Fi模块可以直接利用Wi-Fi联入互联网,是实现无线智能家居、M2M等物联网应用的重要组成部分,属于重要的智能硬件组成部分。

wifi模块是什么  wifi模块有哪些分类

  一、主要分类

  Wi-Fi模块可分为三类:1,通用Wi-Fi模块,比如手机、笔记本、平板电脑上的USB或者SDIO接口模块,Wi-Fi协议栈和驱动是在安卓、Windows、IOS的系统里跑的,是需要非常强大的CPU来完成应用;2,路由器方案Wi-Fi模块,典型的是家用路由器,协议和驱动是借助拥有强大Flash和Ram资源的芯片加Linux操作系统;3,嵌入式Wi-Fi模块,32位单片机,内置Wi-Fi驱动和协议,接口为一般的MCU接口如UART等。适合于各类智能家居或智能硬件单品。

  很多厂家已经尝试将Wi-Fi模块加入电视、空调等设备中,以搭建无线家居智能系统。实现APP的操控以及和阿里云,京东云,百度云等互联网巨头云端的对接,让家电厂家快速方便的实现自身产品的网络化智能化并和更多的其他电器实现互联互通。

  二、应用领域

  串口(RS232/RS485)转WiFi 、TTL转WiFi;

  WiFi 监控、TCP/IP和 Wi-Fi协处理器;

  WiFi 遥控飞机、车等玩具领域;

  WiFi 网络收音机、摄像头、数码相框;

  医疗仪器、数据采集、手持设备;

  WiFi脂肪称、智能卡终端;家居智能化;

  仪器仪表、设备参数监测、无线POS 机;

  现代农业、军事领域等其他无线相关二次开发应用。
