using a PIR with a prop1

[Lynn]

While I am learning about the PROP1....

I have a Quorum PIR...  uses a 9V battery.   

When my program on the prop 1 is finished.   The program re-triggers  without movement in front of the PIR.
Keeps doing this.. just retriggers over and over. 

Jon,  this is the program I had you help me with and finally got going correctly last week.
So, the program is fine, I just am wondering if I can use this PIR with the prop1?
I am still going to use the pressure mat as my trigger on this but thought I would try out the PIR. 

Does the program need something in it in order to use the PIR?

If that's a security system type PIR they are normally closed. Your program would have to look for their to not be closure to start instead of looking for closure on a mat switch.

[Lynn]

Yes, thats exactly what it is.
I could run the PIR through a relay ...?

[gadget-evilusions]

You shouldn't have to. Your program would just be looking for a 0 instead of a 1 to start.

[Lynn]

Would I need to do this?
9v+ ------[22K]------ P6.W
GND ----------------- P6.B  (Note this is connected to the B [ground] pin)
And connect to the black and white rather than the white and red like the mat switch?

And would the jumper be set to UP or DN?

Lynn,

Do you have link to tech docs for the sensor?  It's probably a dry-contact, normally-closed output.  If it is you can connect it a little differently without changing the program code.

Need the docs.

This is all I have....

Okay, use this at your own risk -- hacking into a product at your experience level is not generally recommended.

Based on that documentation, you should connect the black wire output to the Px.B pin (ground) and the red (5v when active) to the Px.W input.  The docs state that the output is on for 2 seconds on detection; that's plenty for the debounce circuit.

Lynn,
    If you can't get your PIR to work, stop by any Radio Shack and pick up a Parallax PIR. They have them for $10 and it will plug right into the three pin connection.

[Lynn]

I'll try that.   I have already soldered wires to the output of the PIR. 
I'll just try connecting to the black and white pins on the prop1.

You might want to try the LED circuit in the docs first -- this will let you verify the action of the device.
