QCA4531作主控,通过增加各类型的传感器实时监测环境数据,以实现动态调节。如增加AMS的ENS210传感器可以实时得到环境的温度与湿度数据以决定是否打开/关闭智能香熏机及调节喷雾的大小,还有增加水位的监测,防止烧干和提醒加水。如果要扩展应用的话,还可以增加麦克风和摄像头用以监控家里的安全。
ENS210 可在0°C 到 70°C 的范围内提供精确度最高达±0.2°C 的开尔文數位温度输出。它还能测量相对湿度,并以數位形式输出,精确度最高为±3.5%。产品在送达客户手中时已经经过校准,因此传感器无需再在生产线上进行调整。产品通过一个I2C 接口提供數位输出,无需应用程序处理器(AP)或微控制器(MCU)进行信号处理。
QCA4531是一款低成本的交钥匙式解决方案,带来高性能的连接方式,能够提供一个用户可编程的Linux/OpenWRT环境,从而使用户从基于2x2 11n扩展的范围中受益。借助Linux构架,该方案可作为功能丰富的万物互联节点,也可以作为枢纽(hub)实现万物互联生态系统。随着万物互联生态系统的发展,QCA4531的出现将成为多协议桥接和通讯的理想选择,可桥接多种无线媒介与不同的生态系统。它可以作为接入点(AP),支持最多16部终端同时运行;
QCA4531可以接入家庭的Wi-Fi路由器设备,透过网络上传数据至云端,让身处在公司或者外面的你可以通过手机/平板/PC上的APP界面了解家里的环境状况。
