Sensor configuration

1. A sensing system for detecting an object, comprising:

a first sensor arrangement comprising:

a first passive sensor, comprising a passive infrared sensor, configured to:

responsive to detecting a presence of an object based upon detecting infrared emissions from the object, send a wakeup signal to a first active sensor for triggering the first active sensor to awaken from a sleep state; and

the first active sensor configured to:

responsive to receiving the wakeup signal from the first passive sensor, transition from the sleep state to an active state; and

while in the active state:

detect at least one of motion or distance of the object within a first detection zone to create object detection data; and

responsive to a determination that the object has physically left the first detection zone, transition from the active state to the sleep state.

13. The sensing system of claim 1 , the first sensor arrangement comprising:

a second active sensor configured to:

responsive to receiving a second wakeup signal from the first passive sensor, transition from a second sleep state to a second active state; and

while in the second active state:

detect at least one of second motion or second distance of the object within a second detection zone to create second object detection data; and

responsive to at least one of a second detection timeout or a second determination that the object has left the second detection zone, transition from the second active state to the second sleep state.

14. The sensing system of claim 13 , the first active sensor and the second active sensor configured to sequentially detect the object to determine whether the object is entering an area or leaving the area.

15. The sensing system of claim 1 , the first sensor arrangement aimed across an entryway.

16. The sensing system of claim 1 , the first sensor arrangement aimed towards an entryway.

17. The sensing system of claim 1 , the first sensor arrangement powered by a battery.

while in the active state:

detect at least one of motion or distance of the object to create object detection data; and

responsive to a determination that the object has physically left a first detection zone, transition from the active state to the sleep state.
