The RAK12027 Earthquake sensor uses the Omron D7S sensor chip. It is the world’s smallest high-precision seismic sensor. Beside of providing seismic data, it also has an alarm output that is activated if a seismic intensity equivalent to 5 or higher on the JMA (Japan Meteorological Agency) Seismic Intensity Scale occurs. This gives the option to shut down sensitive machines and equipment. The D7S sensor detects as well if the horizontal position of the sensor changes, which points towards a collapse of the structure where the sensor was deployed.


  • Based on Omron D7S-A0001
  • Structure collapse detection
  • Using the SI value, which has a high correlation with the seismic intensity scale that indicates the magnitude of an earthquake, provides a higher-precision judgment of seismic intensity scales.
  • Higher degree of freedom for incorporation into devices and prolonged operation on battery power.
  • Shutoff output terminal (INT1) operates equivalent to a conventional mechanical vibration sensor and ensures compatibility with mechanical vibration sensors.
  • I2C interface is able to obtain earthquake-related information from the Sensor with communications from external devices.
  • 3V Power supply
  • Operating Temperature: -30° C ~ 70° C
  • Compact size of 10x23x1mm
