HC SR501 Time Delay Adjustment
3 Seconds Off After Time Delay Completes – IMPORTANT
The output of this device will go LOW (or Off) for approximately 3 seconds AFTER the
time delay completes. In other words, ALL motion detection is blocked during this
three second period.
For Example:
Imagine you’re in the single trigger mode and your time delay is set 5 seconds.
The PIR will detect motion and set it high for 5 seconds.
After five seconds, the PIR will sets its output low for about 3 seconds.
During the three seconds, the PIR will not detect motion.
After three seconds, the PIR will detect motion again and detected motion will once
again set the output high.
