US Patent 10922953 Multiple purpose sensor and security system

A smart home security system is described having multipurpose sensor devices in communication with one more hub devices in further communication with the Internet and wireless carriers. The system is fully autonomous and does not require user interaction to arm and disarm the system, because the system senses and tracks when the user occupants leave their residence and when they arrive. The system also detects if the occupants are sleeping at night and will induce certain settings, such as a universal arming of the system (e.g., ARM STAY), which secures all protected entrances (doors, windows), and disables the motion sensors.
