The system includes a magnet flexibly attached to a strike plate. The strike plate includes an opening. The magnet extends across the opening of the strike plate in a first orientation when a bolt does not extend into the opening of the strike plate. The magnet is configured to be deflected from the first orientation to a second orientation, distinct from the first orientation, in response to the bolt being extended into the opening of the strike plate. The system includes a magnetometer configured to detect one or more magnetic fields of the magnet that is flexibly attached to the strike plate in the first orientation and in the second orientation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sensing system for verifying deadbolt engagement","description":"A door lock detection system is disclosed.
