Many alarm projects are rather simplistic: a single sensor protects a single object or field of view. Such projects are good for learning or practicing simple circuit techniques. But eventually you may wish to have a more advanced / sophisticated alarm system. More like those used by commercial alarm companies. Actually the circuits needed to accomplish this are still fairly simple and can be built around the Adafruit Trinket mini microcontroller.
