Abstract
A motion sensing device adapts a field of view around a primary sensing axis of the motion sensing device by electrically controlling a detection sensitivity of a passive infrared sensor of the motion sensing device. Responsive to adapting the field of view, the motion sensing device monitors for motion within the field of view using the passive infrared sensor.
Claims21
A method, implemented in a motion sensing device, the method comprising:
- adapting a field of view around a primary sensing axis of the motion sensing device by electrically controlling a detection sensitivity of a passive infrared sensor of the motion sensing device;
- and
- responsive to adapting the field of view, monitoring for motion within the field of view using the passive infrared sensor.
A motion sensing device comprising:
- a passive infrared sensor;
- control circuitry communicatively coupled to the passive infrared sensor and configured to:
- adapt a field of view around a primary sensing axis of the motion sensing device by electrically controlling a detection sensitivity of the passive infrared sensor;
- and
- responsive to adapting the field of view, monitor for motion within the field of view using the passive infrared sensor.
A non-transitory computer readable medium storing software instructions that, when executed by control circuitry of a programmable motion sensing device, cause the programmable motion sensing device to:
- adapt a field of view around a primary sensing axis of the motion sensing device by electrically controlling a detection sensitivity of a passive infrared sensor of the motion sensing device;
- and
- responsive to adapting the field of view, monitor for motion within the field of view using the passive infrared sensor.
