The Development of an Earthquake Early Warning System Using an ADXL335 Accelerometer

Abstract

Indonesia is an archipelago located on three earthquake belts. Because of this, earthquakes can happen anytime and threaten human life. A quick and accurate early warning system using seismic wave data processing is required to decrease the number of victims affected by earthquakes. Here, ADXL335 accelerometers are used as seismic sensors with an Arduino minimum system. When the first earthquake vibrations occur, P-wave data detected by the ADXL335 sensor is successfully buffered, calibrated, transmitted and displayed on the server. In case of errors in the transmission, the server will request for retransmission. The alarm of the earthquake early warning system will be activated if at least three sensors from different locations successfully transmit P wave data on the same scale. This is needed to prevent fake seismic wave alarms.
