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.
