Hey @Steve G

PIR sensors emit a high or low signal based on whether there is a change in passive IR in the area or not. They are a digital sensor so a simple script like "getDigital(D0)" will work to see if an event has occurred.

Wow. Simpler than I thought. Thanks Jeremie. I'll give it a try.

@Steve.... PIRs are digital.... If that is a cheap (no offense eBay Chinese one) it may not work very well... Don't forget to use a 5V regulator.... I buy Parallax PIRs... Although more expensive they work perfectly and have a wide voltage range...

We had this very discussion with MovieMaker this morning... LOLPIR detectors and IR detectors

getDigital(D0)

Err, what did I do wrong?

Sorry Steve I forgot to mention you'll need to either assign it to a variable or place it in a condition

ex:

If (GetDigital(D0) = 1)
  Print(One)
EndIf

@RR I believe that unit has a 5V reg on it, I have one like it

Thanks @Jeremie...

@Steve... getDigital(D0) needs to be used like Jeremie said...or you can use a variable...

$movement=getDigital(D0)

@Jeremie.

Thanks bud. All sorted now. :)

@Richard.

Yes mate, it was a "cheap as chips" one from China, but it actually works, now. Had to turn the sensitivity right down to min, otherwise it stays open. I figured as it was less than a pint of beer, it was worth a gamble. (5v reg was connected )

Here's what I used...

:start
If(getDigital(D0)=1)
Print ("On")
Elseif(getDigital(D0)=0)
Print("Off")
Sleep (2000)
Goto(start)
Endif

Thanks again guys. :D

@Steve... awesome man... This is more efficient as you have 2 digital reads without a delay between them...

repeatuntil(1=2)
$move=getDigital(D0) #only one digital read needed
If($move=1)
Print ("On")
sleep(5000) #give the pir time to reset...
Else
Print("Off")
Sleep (250) #speed it up or movement can happen and be gone before the next read
endif
endrepeatuntil

@Steve... you can use the waitforchange command as well if you wanted.... You can modify my script in post #10 to use waitforchange instead...

Thanks Richard. The script I threw togeather was just for a lil testing, but the one you just posted will come in very useful indeed.

Here's a quick vid of the PIR in action.

@Steve... Nice.... Sorry buddy, I am getting as bad as Rich as I am trying to be more efficient... :D

@Richard.

It's all good. Nothing wrong with a bit of efficiency, lol.

@Steve... To be honest, I do like the challenge... But you my friend, don't need much if any help anymore... Both of us will be leaning from other guys now...

@Richard.

Lol, I wouldn't go that far. I still have some potential questions I may need to ask about a couple of other items I want to incorporate (if I can't sort it myself that is).

@Steve G @Richard R

Can someone help me ?

Im a newbie. I want to use my HC-SR501 Mini PIR Infrared Modul. How I connect this modul on the Digital Port ? the pir board has an GND, Output 3,3V and Vcc (5v-20v ) connector. the EZB 4.2 has Sig, Vin and Ground connector.. and after I use the right pins.. how I can read the parameters and how I can use this modul?

I want the same like this video:

thanks a lot
