| Jumper Setting | Mode | Behavior | |----------------|------|----------| | (Repeatable) | Repeat trigger | Output remains HIGH as long as motion continues. Additional triggers during the delay period extend the output HIGH time. Ideal for continuous detection applications. | | L (Non-repeatable) | Single trigger | Output goes HIGH once upon motion detection and will not retrigger during the output delay period. The sensor “locks out” until the delay expires. |

A critical warning often found in technical reports regarding this module involves the voltage regulator. | Jumper Setting | Mode | Behavior |
The output goes high upon motion and drops low after the delay time, regardless of whether the object is still moving in front of it. | | L (Non-repeatable) | Single trigger |
