If they are the Honeywell Aurora PIR type, they are normally used as part of an alarm system. They have small relays inside that either open or close contacts when activated.

A simple way to hack these is to add your own relay (time delay relay) across the LED terminals sine the LED is powered when it is activated. Then you'll have some control of on/off times for your prop.
These are available complete or in various kit forms and are fairly inexpensive.
