Blinker家用多功能报警器以WeMos D1为核核心,外接DCWL-0516微波雷达人体感应模块,DHT11温湿度传感器,GP2Y1014AU粉尘传感器,MQ2可燃气体传感器,和报警
蜂鸣器组成.当室内温度达到到50度或空气质量超过500时,报警器就会给手机发出火警"fire alarm"通知信息.并且报警器的蜂鸣器也会发出报警声.当燃气如果发
生泄漏而触发MQ2时报警器就会给手机发出燃气报警"gas alarm"通知信息.同时报警器的蜂鸣器也会发出报警声.移动侦测报警靠DCWL-0516在其5米范围内被移动
物体触发后即刻向手机发出向移动警"move alarm"通知信息.在手机Blinker app界面上的开关按键可开关移动侦测报警功能.如果家中有人可以关闭它,外出时就可
打开移动侦测报警功能. 报警时不仅可得到通知而且APP上按键的图标也会由绿色的和平鸽变为红色的太阳以示警告.同时右边还有报警次数记录(关闭按键可清零).
程序中空气质量的监测是以前30秒中15次采样的平均值为准的,是可以防止误触发而因起错误报警.再有编程中对WeMos D1的外接端口都采用ESP 8266的GPIO号
来编程的.这样做的目的是使该程序也适合把其它ESP 8266开发板.程序如下:
