Hi all,

I have the same problem,

is there any solution for this ?

Some of websites about product info say "you can adjust this" but there is no info about it

PIR sensors are designed to react slow, to stop false triggering.

If you want to undo that, then you have to change the parts on the PIR board.
Or use a different sensor, like a grid-eye.

Thanks for the answer
But i found 2 different products ;

  1. https://www.mpja.com/download/31227sc.pdf
  2. HC-SR501 PIR motion sensor « osoyoo.com (Features 7)

Delay and blockade times are different in these products,

so their board are different,

so my question is, have can i find second one ? :slight_smile:
