I am looking for a schematic for a simple motion detector. It needs to be
powered by 6vdc to 12vdc. I am going to connect it to 35mm camera.

I have looked at motion detectors that can be bought alone and those that
are used on motion activated lights. Motion detectors alone cost more than
I am willing to pay and the ones used on lights, that I can find, are 24vdc.

You can get Rat-Crap passive infrared security motion sensors alone for
about $20. Would those do, or do you need to sense cold-body objects too?

The ones I've seen have a 24V relay, but the rest of the circuit is
usually lower, sometimes only 5VDC. So if you replace the relay, it
should work at 6 or 12V.

There's a PIR motion detector with a radio link to the X10 system.
Runs off two AA batteries. No reason you couldn't pick off a signal
inside to trigger your camera. Can't find it, so can't give you the
model number.

How much are you willing to pay?

By the time you have to buy all the parts, the optics, a box to put it
all in and assemble and test it, it will have cost you a lot more than
just buying one.

What do you want to detect, anyway? Humans? Animals?

From how far away?

From how far to the side?

Indoors?

Outdoors?

Summer?

Winter?

I saw an item on British TV today which was a very brief review
of kitchen 'swing-bins' and one of them opened its lid just as
the user approached it and took him by surprise. So there's something
out there which costs very little to make that should be adaptable but
I have no other information than that.

Thanks! This is what I was looking for.
