Earthquake Sensor Omron D7S | RAK12027

Description 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. Features 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 mechan
