ATEQA2015, a household earthquake alarm, is designed to be used as an auxiliary alarm, to give a warning signal before and during the earthquake occurs. Itpredicts the earthquake by sensingthe variables such as geomagnetism loss,magnetic north and south poles reverses, and the vertical P wave. This can gain seconds or more warning time before the earthquake arrives.
The signal processing circuit inside can distinguish effectively between the P wave signal and other vibration or sound signals to avoid false alarm.
