The access sensor for doors and windows works with a smart home security system to alert homeowners when a door or window is left open. The wireless sensor's highly sensitive detection technology can recognize when a door or window is opened an inch or more. Monitor a home at each access point with the access sensor for doors and windows. The wireless door or window sensor discreetly watches one door or window and sends an alert when it opens an inch or more. If a homeowner leaves, the smart home security system can send a reminder if the door or window is left open, helping keep the home secure.
