1. A motion sensor assembly, comprising:
a cover plate comprising a cover plate aperture that permits a portion of an electrical component in an electrical box to pass through the cover plate when the cover plate at least partially covers the electrical box;
a temperature sensor;
a motion sensor;
a communication device; and
circuitry comprising a controller, wherein:
the controller is configured to receive motion signals from the motion sensor,
the circuitry is configured to adjust a voltage window based on a temperature sensed by the temperature sensor,
the controller is configured to compare the motion signals to the voltage window that specifies a range of amplitude sensitivities,
based on the range of amplitude sensitivities, the controller is configured to cause the circuitry to reject signal amplitudes of the motion signals associated with motions of animals and accept signal amplitudes of the motion signals associated with motions of persons,
the circuitry is configured to filter frequencies associated with the motions of the animals from the motion signals to obtain filtered signals and detect movement based on the filtered signals, and
the communication device is configured to transmit an indication of the detected movement.
