Grove PIR sensor is too sensitive!

Hey guys,

I’ve been fiddling around quite some time now with the Grove sensors, (I’m teaching children the awesome world of electronics)
but the grove sensor is just too darned sensitive! Even if I set a cardboard box right covering the entire Grove board, it still keeps going off. Turning the range down just doesn’t work, I need the long range (3~5 yards).
I don’t understand a thing about the ‘Time’ settings. The H and L switch is also a big clue for me…
Does anybody know what the problem is?

If you can, please post your picture then can see what problem with you.
According the sensor feature, that can adjustment with sensitivity.

Hope can help you, if any problem, please further feedback more.
