actualy I’m working on the PIR at the moment
I had ordered some new PIR’s with a very short (1.8 sec) delaytime.
That’s the time the output stays 'one after movement detection.
The signal wakes up the 32U4 (leonardo) processor and trigger an LoRaWAN alarm signal.
This very low current type has no adjustable time but you can order them between 1.8 sec and 1 hour delaytime.
Nice, now the processor can go to sleep faster, in the code I can set a counter or timer to prevent sending constant alarmsignals when a burglar is walking in the room.
And, if necessary I can count people
