Using Pir On Digital Port

Skip to comments   Jump to end

Hey guys.

I need a little help with a small PIR sensor I picked up. Operating voltage is 4.5 v upwards so have it plugged in to D0 as analog won't be enough to power it (tried it on ADC0 but voltage meter shot up to 220). Could someone offer me a Short script example for me to work from to test if the sensor is working? I had a quick look on the forum but the very few entries I found were regarding ADC.

Many thanks.

@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.

@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
