You need a 4-input NOR GATE http://engin.swarthmore.edu/~ejaoudi1/datasheets/7425.pdf
and a 3.3V to 5V level shifter to shift the PIR outputs for the nor gate . You can't connect the sensors directly to the Nor gate.
Know one has used these
does anyone know were I can get a face plate or wall or ceiling plate to mount this ?
You won't find any. You have to use something that was made for something else. In other words, you have to use your imagination.
Do you want a hint ?
(what does almost every room have in a house owned by a fire-safety conscious person that no one looks at twice ? (besides a light bulb)
Your talking about a smoke detector. If you are that would be expensive to buy one and remove the inside. Can you buy just the shell
Maybe you can find one that has been discarded or in a garage sale.
ok your right thats a good idea. My wife loves going to yard sales and this is the right time of the year have a good one
