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.
PIR sensor
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.
Err, what did I do wrong?
ex:
Code:
@RR I believe that unit has a 5V reg on it, I have one like it
@Steve... getDigital(D0) needs to be used like Jeremie said...or you can use a variable...
Code:
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...
Code:
Thanks again guys.
This is more efficient as you have 2 digital reads without a delay between them...
Code:
Here's a quick vid of the PIR in action.
It's all good. Nothing wrong with a bit of efficiency, lol.
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).
@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
