Abstract
A multi-purpose alarm operates in a motion-detected alarm mode and a motion-expected alarm mode. In the motion-detected alarm mode, when the multi-purpose alarm is touched or moved, an alarm is issued. In the motion-expected alarm mode, when the multi-purpose alarm has not been touched or moved for a period of time, an alarm is issued. The multi-purpose alarm employs an accelerometer to sense the presence or absence of movement and is attachable to an object being monitored through various attachment means including a spring clamp, an adhesive, and a magnet.
