The Vibby OAK Fall Detector offers enhanced versatility and wearability options. It incorporates a manual alarm button along with a micro-controller, 3-axis accelerometers, a vibrator and a radio transmitter. In the event of a fall, it will vibrate and the LED light will flash for a grace period of 20 seconds. Unless the user cancels the alarm, or gets up and remains standing, the fall detector will send an alarm to the alarm receiving centre via the Careium social alarm. The sensor is waterproof to IP67, shock resistant, made of hypo-allergenic plastic and has a replaceable battery.
