Motion Sensor Detector — Wireless Movement Alarm for Home Automation, App-Controlled, High Sound

Monitor door and window opening and closing from your phone. This wireless motion detector reports each door/window status to the companion app, and if you deploy multiple sensors around your home you’ll see all locations’ states displayed at once for quick at-a-glance monitoring. The system sends a smartphone notification when battery power runs low so you know when to replace the battery. Installation is simple: power the unit, open the app and add the device — DIY setup in minutes.
