The H3 Human Presence Sensor uses millimeter-wave radar technology to accurately detect human movement, standing, and even static presence.
Detects Subtle Human Movements
It can detect subtle human movements such as breathing and micro-motions, significantly improving presence detection accuracy.

Harvesting directly its energy from your push, the Door and Window Sensor doesn’t need any battery (and any wire) to operate
Advantages of a wireless system (flexibility) without the disadvantages (no battery = no maintenance)
This Door and Window Sensor can be mounted concealed in the door frame, it also can be mounted externally on the surface of door and being fixed with screws
Mount it, and forget it
