How Fall Detection Works and When It Might Miss a Fall

Fall detection uses sensors like accelerometers and gyroscopes in wearable devices or smart home systems to detect rapid motion changes and impacts, then sends alerts. But it can miss falls if the movement is too slow, like a gradual collapse, or if the device isn’t worn properly—think a lifepod left on a nightstand. Background vibrations from a door slam or a sudden sit-down can also confuse algorithms, leading to false alarms or no alert at all.
