Features:

The trigger mode of these mini human sensor modules:
After high sensing output, during the delay time, if a human body is active within its sensing range, its output will keep high until the delay after the people leaves, then it will become low.
The human sensor module will prolong a delay time cycle automatically after detecting every activity of the human body, and the time of the next activity is applied as the starting point for the delay time.
