The names of acnFind and acnAlert are almost self-explaining. The beacons need to be attached to an object in order to be found. Both beacons are equipped with an accelerometer by STMiroelectronics. It measures motion, vibration, shock and free fall. If any of the actions mentioned above occur, there will be an alert. The acnFind can give visual and acoustic feedback by flashing and buzzing. More detailed information is given in this video.
