Triggering the detector

Figure 10 – most

sensitive trigger

In figure 10, a body moving from position 1 to position

2, into the infrared beam zone, will create a pulse.

Moving from position 2 to 3, out of the other side of

the same infrared beam zone, will create another

pulse. If the body moves from position 1 to position 3

within 10 seconds then the det

ector will have

received 2 pulses in 10 seconds. This means the

detector will have made a valid movement detection

and will trigger, indicated by the red light. This also

applies if the body moves in the opposite direction.

No trigger body movements

Figure 11 – no

trigger

No trigger body movements are body movements

which are too small to be recognized as valid body

movements to trigger the detector.

In the example, shown by figure 11, a body walking

into one side of the

infrared beam zone, then back

out the same side of the infrared beam zone will not

trigger the detector. A body moving from position 1 to

2, into the infrared beam zone, will only create

pulsing. A body moving from position 2 back to

position 1 or from po

sition 2 to position 3 (out of the

same side of the infrared beam zone) may create

further pulses but will not trigger the detector. This

also applies if the body is moving in and out of the

infrared beam zone from the other side.
