hi guys...
I'm very beginner in electronics..
I'm experimenting with PIR module
I've also build a circuit and it works well, so there's a problem.
when ever a moments occurs the beep goes on (its ok ) but it re- activates in 5 seconds to recognize the next moment.
its very annoying...
so my question is how to delay the re-activation from 5 seconds to 30 seconds.?
Is 555 timer is helpful here..?
 

cascade a 30 and 5 second vibrators so that the first one can be fired after the 30 secs.. and that triggers the 5 sec vibrator at output...
